Two different speeds of hole expansion tests were conducted within the quasi-static range, accompanied by a uniaxial tension test with a deformation mode similar to hole expansion for supplementary analysis. Finite element simulation was utilized to analyze the detailed deformation behavior within the material, particularly at the hole edge where cracks occur during hole expansion. The mechanical and fracture properties obtained from the uniaxial tension test were incorporated into the simulation, taking into account the anisotropy of the material to predict the precise location of crack initiation within the hole edge. To account for the strain rate effect on the experimentally determined hole expansion ratio, a ductile fracture model was introduced and its necessity was validated by considering the occurrence of material fracture before and after crack initiation. By utilizing 3D solid elements, considering material anisotropy, and applying the ductile fracture model, the simulation provided reasonable predictions for the hole expansion ratio, which exhibited variation with strain rate.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 17","pages":"18886 - 18899"},"PeriodicalIF":2.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-024-10601-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The final shape memory polymer composite (SMPC) device has been manufactured by lamination and compression molding, with a size of 20 × 45 mm². A single molding step has been adopted to co-cure the CF prepreg plies with the SMP interlayers and to join them to the foam elements and the embedded heater. Foams have been manufactured by solid-state foaming of the same SMP epoxy resin of the SMP interlayers. The SMPC-NEA has been tested in memory and constrained-recovery tests to evaluate the effect of the heater supply voltage (from 20 to 24 V with 1 V increments) and the loading rate of the memory stage (1, 5, 10, 20, and 50 mm/min). Many important shape memory (SM) characteristics have been extracted by the tests, with some important correlations. A master curve has been also built to show that the superposition between the supply voltage (related to the device temperature) and the test rate (related to the observation time) is possible. The regular shape of the master curve also shows that severe damages were absent during testing, with 25 memory-recovery consecutive cycles. In the best case, the SMPC-NEA applied a recovery load of 7.4 N.

Selective laser melting was used to prepare titanium-alloy honeycomb samples. Experiments on compression mechanics were performed in a single-axis plane. A periodic crushing and unloading phenomenon occurred in the platform section. The structural deformation mode and fracture failure mechanism were analyzed by combining a digital camera and a scanning electron microscope. The influence law of wall thickness on the crush unloading of honeycomb was studied based on parameterized finite element numerical analysis. When the self-similar honeycomb of titanium alloys was suffered from in-plane compression, the fracture of the honeycomb edge joint in the structural shear zone area caused periodical crush unloading of the structural stress–strain curve. Obvious tough dimples were observed at the fracture of the failure site, showing obvious plastic-failure morphology. Proper wall thickness thinning increased the rotation angle of the honeycomb’s short side during failure and reduced the minimum bending radius. Besides, it improved crush unloading as well as the bearing stability of the structure. When the relative density was 0.23 (with the wall thickness of 0.11 mm), self-similar honeycomb had optimal structural stability and the highest crush loading efficiency.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 17","pages":"18946 - 18953"},"PeriodicalIF":2.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, optimizing the cold spray process for metallizing thermoplastic polymers is a complex task due to the numerous interacting parameters that influence coating quality. As traditional trial-and-error approaches are time-consuming and costly, machine learning (ML) could offer a solution to these challenges by providing further insights into the process and enabling more efficient optimization. The aim of this work is to identify the most relevant input parameters for ML models, with a particular focus on powder characteristics, to predict two critical outcomes: particle flattening and penetration depth. Two distinct datasets were created for this study: one focused on particle yield strength and the other on powder density, each combined with further input parameters like impact velocity and substrate yield strength. These datasets were constructed using experimental data and finite element modeling (FEM) simulations, with materials including copper, aluminum, titanium, and others, applied to thermoplastic substrates like polyether ether ketone (PEEK), acrylonitrile butadiene styrene (ABS), and polyamide 66 (PA66). Several ML algorithms, including decision trees, neural networks, and Gaussian process regression, were tested to predict coating behavior, and the effects of Z-score normalization were evaluated for improving model stability and prediction accuracy. The results show that particle yield strength is crucial for flattening, while particle density primarily governs penetration depth. This study demonstrates that ML, when combined with a solid understanding of the process, offers an effective framework for optimizing CS deposition on polymers.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 8","pages":"6527 - 6538"},"PeriodicalIF":2.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-025-11096-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To optimize their performance in high-demand environments, surface functionalization of vitrimers and vitrimeric composites is crucial to enhance their durability and reliability in harsh conditions. This research work aims at studying the feasibility of metallising vitrimer-based components through cold spray technology. Aluminium coatings were applied under varying process parameters, inlet gas temperature (<i>T</i> = 150 –450 °C) and standoff distance (SoD = 70 mm–100 mm), to evaluate their impact on deposition quality and substrate behaviour. The deposition processes were performed on non-reinforced vitrimeric substrates as well as on vitrimeric matrix substrates reinforced with carbon fibre fabric. The results suggest that successful metallization occurs when the substrate temperature exceeds the topology freezing transition temperature (Tv ≈ 170 °C), enabling the ductile behaviour necessary for effective adhesion.

Surface roughness increased from Sa = 0.15 ± 0.05 µm for uncoated substrates to Sa = 6.59 µm after coating. In contrast, composite substrates demonstrated enhanced stability due to fibre reinforcement, which constrained excessive substrate flow. At the best process conditions (<i>T</i> = 300 °C and SoD = 100 mm), composite panels achieved homogeneous coatings with Sa = 4.513 µm.

The comparison between the CFRP tubular structure and traditional aluminum alternative was conducted to identify the most sustainable solution. The analysis showed that the CFRP tubular component resulted in lower environmental impacts than the traditional alternative (i.e., about 70% lower considering the whole life cycle) mainly due to the reduced weight.
