Simulation of the eddy current (EC) testing of the sandwich structure using the finite element (FE) method is challenging as the traditional FE method has difficulties in mesh division and the solution of the algebraic equations. This paper proposes to use the domain decomposition FE method to solve such problems. The top CFRP panel, the aluminum honeycomb core, and the bottom CFRP panel of the sandwich structure and the ferrite core of the coil are placed in different subdomains and the subdomains are meshed independently. This method simplifies the mesh generation and does not require regenerating the meshes when simulating the scanning testing with the ferrite-core coil. In this way, the efficiency of simulation is greatly improved. The EC distributions in the sandwich structure are computed and the influence of defect on EC distribution is analyzed. The C scans of the sandwich structures are simulated. The images of the EC responses to the defects, such as wall fracture, node disconnection, and core wrinkle, are obtained. The simulation results are validated by experiments.</p></div>","PeriodicalId":655,"journal":{"name":"Journal of Nondestructive Evaluation","volume":"43 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140560562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A fully non-contact test setup is used to investigate differences in the volumetric porosity between AM AlSi10Mg samples. A set of 96 samples with programmatically induced pores varying in nominal total porosity between 0% and 2% is tested: one half of the samples are prismatic, and the other half have a complex internal Triply Periodic Minimal Surface (TPMS) structure. In addition, a subset of the samples is scanned using X-ray micro-computed tomography (µ-CT). It is found that the resonance frequency corresponding to the 1st compressional mode can predict the total nominal porosity even in TPMS samples. From statistical analysis, the smallest detectable porosity difference is found to be 0.25% for the prismatic samples and 0.5% for the TPMS samples. The experimental results agree well with the predictions of finite element (FE) simulations and analytical models. However, X-ray µ-CT appears to underestimate the porosity, possibly due to its inability to resolve the small pores.

The mechanical properties of the materials were obtained by monotonic tensile tests on coupons with different directions of loading relative to the deposition direction. Then, 36 connecting specimens with two printing layer orientations and varying dimensions were tested to failure. The stress-induced magnetic fields around the specimens were monitored online by magnetic probes throughout the loading process. It is found that the anisotropy of WAAM steel can be observed from the piezomagnetic response. The failure modes of lap connections include net section tension, end-splitting, shear-out and tilt-bearing. The results show that the magnetic response exhibits similar behavior to the mechanical response. It is possible to predict the failure mode of the specimens using the magnetic field-displacement curve.

The presence of noise makes the use of these methods unreliable. Therefore, it is necessary to develop and apply a robust technique in noisy conditions. The main purpose of the proposed method in this study is to investigate the effect of noise on highway bridges and reduce its effects in determining the precise and correct location and severity of damages on these types of bridges. Therefore, a dual-criteria method based on modal flexibility change (MF) and modal strain energy (MSE) damage index is considered as the bases for training convolution neural network (CNN). This method aims to identify more accurate the damage location and intensity with and without the effect of noise. The feasibility of the proposed method is indicated on a validated FE model applied to the portion of the I-40 bridge as a sample of steel girders highway bridge by its application to a range of damage scenarios. The numerical simulation of damage scenarios is utilized to achieve both noise-polluted damage indexes for training CNN. The well-trained CNN is then applied to double-check the location and attain the intensity of unknown single and multiple damages (up to four simultaneous damages) in noisy conditions. The results demonstrate that dual criteria damage indexes along with CNN can practically and accurately identify unspecified location and severity of single and multiple damage scenarios in the presence of noise.</p></div>","PeriodicalId":655,"journal":{"name":"Journal of Nondestructive Evaluation","volume":"43 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140315347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For retrofitting purpose, non-destructive assessment, which does not cause additional damage to structures, is preferable compared with destructive assessment. In this direction, non-destructive assessment of postfire RC frames was performed in this study. To achieve this aim, experiments were performed on eleven full-scale RC frames, included one, five, and other five frames exposed to 0 (control), 45 min, and 75 min of fire, respectively. These two fires had similar maximum temperature, but the 45-min fire had higher increasing rate of temperature (IRT). After fire exposure, methods of Schmidt rebounding, ultrasonic, and vibration tests were used to perform non-destructive assessment by comparing the results of postfire frames against the control frame. The results showed that the explosive spalling of concrete mainly occurred between 5 and 12th min and then proportionally decreased with the increase of fire duration. The IRT outstandingly affected the explosive damage of RC frames. The higher IRT resulted in higher cracking and explosive spalling of concrete; IRT is thus an important parameter to represent the severity of fire. The experimental non-destructive data was analysed and compared to provide some information on the assessment of postfire RC frames, which can be useful for decision making.</p></div>","PeriodicalId":655,"journal":{"name":"Journal of Nondestructive Evaluation","volume":"43 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140152408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use this to propose a method to analyze the comprehensive index of fracture-induced AEs of red sandstone based on information entropy. A comprehensive index to characterize the tensile and shear failures of rock was obtained by quantifying the entropy weights of the characteristic parameters of AE and their laws of evolution were analyzed. Areas for the classification of different cracking mechanisms of rock were established based on the Box–Cox transform, and the fractal features of crack development under compression–tension and compression–shear conditions were analyzed by using the Grassberger and Procaccia (G–P) algorithm. The results showed differences in the entropy of the characteristic parameters of red sandstone in cases of tensile and shear damage, with the rise time and energy recording the maximum entropies, respectively, and the amplitude yielding the minimum entropy. The comprehensive evaluation indices for tensile failure <span>(xi_{t})</span> and shear failure <span>(xi_{tau })</span> confirmed the existence of at least two mechanisms of deformation-induced damage—tensile fracture and shear slip—in the process of damage to the rock. The curve of evolution of the fractal dimensions <span>(D_{t})</span> and <span>(D_{tau })</span> of compression–tension and compression–shear, respectively, followed the law of continuously decreasing dimensions, and their turning points reflected the change in crack development in the rock.</p></div>","PeriodicalId":655,"journal":{"name":"Journal of Nondestructive Evaluation","volume":"43 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140152727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
