The varying temperature influences the performance of the inspection system inducing false alarms or missed detection, with a consequent reduction of reliability. This paper quantitatively assesses two temperature compensation methods, namely the optimal baseline selection (OBS) and the baseline signal stretch (BSS), with the aim to extend their use to the case of distributed sensor networks (DSN). The effect of temperature separation between baseline time-traces in OBS and BSS are investigated considering multiple couples of sensors employed in the DSN. A decision strategy that uses frequent value warning to define the optimal baseline or stretching parameter is found to be effective analyzing data from two several experiments, which use different frequency analysis with either predominantly A0 mode or S0 mode data or both. The focus is given on the fact that different paths are available in a sensor network and several possible combinations of results are available. Nonetheless, introducing a frequent value warning it is possible to increase the efficiency of the OBS and BSS approach making use of fewer signal processing algorithms. In addition, the effectiveness of those approach is quantified using damage indicators as metric, which confirms that the performance of OBS and BSS quantitatively agree with predictions and also demonstrate that the use of compensation strategies improve detectability of damage with a higher reliability of the system.","PeriodicalId":276311,"journal":{"name":"2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115133263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to poor interlaminar strength, composite components are prone to barely visible impact damage during aircraft operation. Sparse array guided wave imaging, using a network of distributed sensors, is an important Structural Health Monitoring (SHM) tool for the detection and localization of in-service damage in composite structures. However, the anisotropy of composite laminates influences guided wave scattering, impacting imaging performance. Defect characterization can be improved by considering the scattering characteristics of various damage types for the sparse array signal processing. Guided wave scattering (A0 Lamb wave mode) was investigated around an artificial insert delamination in a quasi-isotropic carbon fiber reinforced polymer (CFRP) panel. Permanent magnets, mounted on an undamaged region of the plate, were also used as scattering targets and compared to the delamination case. Full 3D Finite Element (FE) simulations were performed for both the delamination and magnet cases and compared to wavefield data obtained from non-contact laser measurements. Good agreement was found between the experimental measurements and simulations. Scattered guided wave amplitudes around each damage type show strong directional dependency with energy focusing along the fiber directions of the outer ply layers of the laminate. Distinct scattering behavior was observed for each damage type. A forward scattered wave was observed for the delamination, whereas the magnet blocked forward wave transmission. Implications of anisotropy and angular scattering on sparse array SHM of different defect types are discussed.","PeriodicalId":276311,"journal":{"name":"2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123389159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on guided-wave propagation in 3D-printed components and their sensitivity to damage. The material under investigation is 3D-printed poly(lactic acid) (PLA), which was used to manufacture flat plates. Several plates were prepared with varying infill densities. Lower infill density allows to save printing material, but it influences the guided-wave propagation behavior. To study the damage localization capability, plates with and without internal artificial defects were prepared. For each infill density, a healthy and a damaged plate were prepared. The guided waves were excited in the plates using surface-mounted piezoelectric transducers, while the sensing was realized by a scanning laser Doppler vibrometer. Five-cycle-long tone-burst excitation signals of different central frequencies were used, for comparison, where it was demonstrated that lowering the plate's infill density results in the appearance of higher-order modes at lower cut-off frequencies. Additionally, it was shown that guided-wave-based imaging can reveal hidden flaws and even the inner structure of 3D-printed polymers. This shows the good potential of guided-wave-based techniques for the structural health monitoring of 3D-printed structures.","PeriodicalId":276311,"journal":{"name":"2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123914540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In prior investigations the SPC-I technique is performed by exciting a wideband sweep signal through the material. Although this is a good general approach, the SPC-I technique can be fine-tuned for specific specimens under investigation. In this investigation, a single frequency is selected as an excitation signal that is propagated through the composite plate specimens. This single frequency is experimentally defined using a pristine composite plate as a control specimen. Multiple signals are propagated through the pristine specimen at a range of frequencies in order to find the sensitive frequency. By applying the SPC-I technique on the range of signals obtained for the pristine specimen, a single fine-tuned frequency can be identified that can be used to detect and monitor impact damage in composite plates. In this investigation glass fiber composite plates that are impacted with increasing impact energy (0J, 5J, 10J, 20J, 30J, 40J and 50J) are examined using the fine-tuned excitation frequency coupled with the NLU SPC-I technique.

Inversion of multiple spacings and multi-frequency non-collocated measurements in centralized settings [2] gives good results for up to four centered pipes but the quality of results is severely compromised by casing and tool eccentering (limiting maximum utilizable frequency for interpretation), and by ghosting effect (double indication of same heterogeneity – limiting reliability near casing collars).\u0000 In this work, the impact of approaching anomalies and eccentering, as typically encountered while logging a multi-casing oil and gas well, will be analyzed in detail through 3D modeling studies and advanced processing schemes introduced to address these issues.","PeriodicalId":276311,"journal":{"name":"2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121851194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is particularly difficult to monitor concrete structures due to their non-linear nature and random distribution of constituents. Evaluation of properties of concrete as a heterogeneous composite has been performed by various techniques ranging from highly sophisticated physicochemical characterization to mechanical tests. The linear ultrasonic techniques generally measure the time-of-flight or the attenuation of a propagating wave. In recent years, the non-linear ultrasonic techniques have been proven to overcome some of the challenges during concrete curing monitoring. In this investigation, ultrasonic testing is carried out on concrete prism specimens. The specimens are placed in a 4-point loading machine and stressed until failure. Ultrasonic signals are propagated through the specimens using tuned PZT transducers in a transmission mode. The ultrasonic testing is carried out in a continuous real-time way to allow real-time prediction of specimen deterioration before its catastrophic failure. The results show that the traditional linear ultrasonic techniques (such as the first-arrival technique and signal attenuation) cannot detect concrete deterioration before its failure . However, the non-linear ultrasonic technique, i.e., the Sideband Peak Count-Index (SPC-I), is sensitive enough to detect concrete deterioration before its failure. Therefore, the SPC-I technique can be deployed for continuous reliable monitoring of concrete structures.","PeriodicalId":276311,"journal":{"name":"2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121053315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for practical applications a quality assessment is necessary to estimate damage detection capacity and probability of the designed SHM system. Such evaluation of a general overview for an arbitrary structure is limited with experiments due to repetitive wavefield measurements. Validated numerical analysis tools must be used. In this work, validation study for a complex composite structure with Elastodynamic Finite Integration Technique (EFIT) will be presented. As reference model the measurement data coming from the Open Guided Waves Project (OGW) was selected. The dataset consists of measurements for two different cases called local and large stringer debond with additional baseline measurements. Within this contribution this experiment is reproduced by simulation using EFIT. Results show a good match between the experimental and simulated datasets, as the input parameters are fully determined prior to the simulations. The paper motivates further research, for example related to probability of detection analysis and numerical performance of the results.","PeriodicalId":276311,"journal":{"name":"2022 49th Annual Review of Progress in Quantitative Nondestructive Evaluation","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115746292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
