Composite materials reinforced with natural fibers, such as flax, offer a sustainable alternative to traditional materials. However, they still face limitations in mechanical performance and durability compared to synthetic fibers like carbon. 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}

Making use of the appropriately defined incubation times and stress invariants that are commonly involved in formulation of the quasi-static failure criteria, their dynamic counterparts can be delivered.

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. Furthermore, the identification of optimal process parameters and setups, as well as the analysis of bonding phenomena, provides valuable insight into the effective implementation of the process in the aluminum recycling industry.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 12","pages":"11293 - 11311"},"PeriodicalIF":2.0,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161578","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}

Given the diminutive size and weight of MEMS devices, the contact force between the surfaces of MEMS components can lead to several problematic scenarios during the assembly procedure, such as the undesirable adhesion of the MEMS surface components. 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}

This work has two aims; (i) to perform Quasi-static (QS) and Low-velocity impact (LVI) tests to calculate a novel predictive parameter, the Dynamic scaling factor (DSF), defined as the ratio of LVI to QS results. The DSF allows the prediction of the impact behaviour by easier and lower-cost quasi-static tests. (ii) to evaluate the feasibility of Aluminium honeycomb sandwich (AHS) as a new sustainable alternative to composite sandwich. The mechanical tests were carried out using two different tups, hemispherical and conical, and damage detection employed Non-destructive techniques (NDT), specifically x-ray digital radiography. Two ‘traditional’ composite sandwich solutions, a thinner, lighter GFRP/PVC laminate and a thicker, heavier GFRP/balsa one, were compared with two AHS panels of equivalent bending stiffness to the composite sandwiches. For the perforation of the upper face only, results indicated that AHS absorbed more energy. If the complete perforation of the whole sandwich is considered, GFRP/PVC and GFRP/balsa sandwich composites absorbed more energy. The DSF was found to be greater than or equal to unity, varying between 1 and 2, depending on laminate thickness, material, tup geometry, and damage level considered. When perforation of the first skin is important, AHS can provide a new viable high-performance lightweight alternative to ‘traditional’ composites in terms of impact strength whilst providing a more sustainable alternative. This makes AHS a valuable new material choice in marine applications that emphasises weight reduction, energy efficiency and recyclability.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 15","pages":"15376 - 15388"},"PeriodicalIF":2.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832096","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}
