Composite materials reinforced with natural fibers, such as flax, offer a sustainable alternative to traditional materials.

In this context, hybridization offers a promising strategy for reducing the carbon footprint while preserving material performance. This study begins by investigating the impact properties of carbon/ and flax/epoxy laminates through a combined experimental and numerical approach. Specifically, the in-plane crashworthiness of flat samples is evaluated to determine their energy absorption capabilities and to extract material parameters for modeling using LS-DYNA software. In addition, both experimental and numerical investigations are conducted on the axial crushing behavior of circular tubes, including also hybrid carbon-flax composites, to further assess crashworthiness and examine the influence of the geometric shape of components. Macro-scale and meso-scale numerical models are developed and validated against experimental results. The meso-scale models, in particular, demonstrate a superior ability to accurately replicate load-displacement responses and failure mechanisms, confirming their reliability in predicting the behavior of these materials under impact conditions.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 15","pages":"15397 - 15413"},"PeriodicalIF":2.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832112","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}

Numerical methods for calculating sensitivities, such as finite difference methods, are often easy to implement but can suffer from high computational costs and limited accuracy. Continuum Sensitivity Analysis (CSA) is an alternative approach for calculating analytical derivatives with respect to shape or value parameters. It is easy to implement and can be as accurate as conventional analytical sensitivity methods. By employing Spatial Gradient Reconstruction (SGR), continuous sensitivity equations can be solved in a nonintrusive manner. This method has been applied and validated on a wide range of problems. This work aims to extend the range of applicability of CSA to composite laminates. Composite materials may be characterized by several cross-coupling between loads and deformations, which leads to complex stress fields. A general formulation is introduced that applies to any plate-discretized Finite Element (FE) problem. The developed methodology utilizes the plate elements’ resultant forces and moments instead of the stresses to reconstruct spatial gradients and apply boundary conditions. Because of that, the method does not depend on the material type or lamination sequence and is also computationally inexpensive. It can be used indifferently for isotropic or composite materials, with any lamination sequence. This feature makes CSA attractive for classical FE models used in design optimization problems. This novelty extends the range applicability of CSA to any possible plate-based structural problem.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 15","pages":"15359 - 15375"},"PeriodicalIF":2.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-025-11258-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832162","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}

In this study, a thorough analysis was conducted on various geometries of the extruded parts, process parameters and setups: the direct and inverse traditional hot extrusion and the Friction Stir Extrusion processes. Moreover, a comprehensive evaluation of all the components contributing to the energy demand of both the traditional hot extrusion process and the Friction Stir Extrusion was conducted. To accomplish this, the same simulation model was developed and adapted for each process, extracting the data to evaluate the energy consumption related to axial thrusts, rotational forces in Friction Stir Extrusion, and preheating in traditional extrusion. Through the comparison of the obtained results, it was possible to discern the specific geometries, setups, and parameter combinations for which Friction Stir Extrusion demonstrates superior energy efficiency in contrast to traditional extrusion and vice versa. The study’s findings suggest that the Friction Stir Extrusion offers significant advantages over traditional recycling methods, enabling the production of high-quality extruded parts with reduced energy consumption, only if some certain conditions were considered. In particular, only when comparing the same extruded mass (7 g) for both technologies, Friction Stir Extrusion proved to be significantly more energy efficient in all scenarios, as only half (for lower descent tool feed) and a quarter (for higher descent tool feed) of the specific energy of the traditional extrusion process is required to complete the process.

This can negatively affect the assembly procedure and result in incorrect positioning of microparts. Therefore, reducing the adhesion force is essential for enhancing micro-assembly. This research aimed to explore the impact of angularization of the interstitial layer and the last layer on surface morphology, surface roughness parameters, and adhesion using the glancing angle deposition method. To achieve this, six samples were simultaneously layered with varying experimental angles of 0, 30, 45, 60, 75, and 85 degrees for the deposition of thin films. These films comprised a titanium interstitial layer and the main layer Ag-Pd (0.9 wt.%)-Cu (1.0 wt.%). Following the glancing deposition, the morphology of the films was examined using SEM, while the layer roughness and adhesion force were determined using AFM. The findings of this study revealed that increasing the angle of the referenced layer resulted in an initial increase and subsequent decrease in both the grain height and surface roughness of the silver alloy. The tests showed that the angle of 85 degrees corresponded to the lowest level of adhesion observed in both experiments. In conclusion, it can be inferred that adjusting the angulation of the Ti interstitial layer in relation to the angulation of the last layer of the silver alloy results in improved grain size distribution, increased grain height, and enhanced regularity in surface adhesion behavior.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 18","pages":"20075 - 20084"},"PeriodicalIF":2.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090316","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}
