The metal-based 2D auxetic lattice structures hold the potential for multifunctional tasks in aerospace applications. However, compression response of those manufactured by powder bed fusion process is underexplored. This study proposes a comprehensive comparison in-plane quasi-static performance structures, utilizing three designs (anti-tetrachiral (ATC), double arrow-headed (DAH), and tree-like re-entrant (TLR)), with stiff Ti6Al4V electron beam (PBF-EB) various manufacturing speeds....
In the present study, a comparative compression investigation of anti-tetrachiral and modified re-entrant lattices was conducted in-plane direction using experimental numerical analyses. Lattice structures were manufactured fused deposition modelling 3D printing technology crushed at quasi-static condition. Nonlinear finite element (FE) models both established, FE results systematically compared with results. The onset densification phases determined numerically. Results indicate that...

A variety of 3D printing parameters have been investigated including reinforcement material and print orientation, as well pattern, distribution volume. From these evaluated parameters, the optimal values are taken into account to select highest compressive properties. By using Scanning Electron Microscopy (SEM) imaging, thermoplastic layers clearly identified alongside sample flaws. Horizontally printed samples exhibited higher mean with less standard deviation than vertically ones for...
The 2D double arrow-headed (DAH) lattice structures, which are promising cellular structures for impact mitigation, remain relatively unexplored in terms of their compression response when manufactured using the powder bed fusion process with Ti6Al4V (Ti64) alloy. This study aims to investigate effects build orientation and beam scan speed Electron Beam Powder Bed Fusion (PBF-EB) on energy absorption Ti64 DAH structures. Additionally, potential microstructural variations due adjusted...
In this study crashworthiness optimization of nested and concentric circular tubes under impact loading is performed by coupling Finite Element model, Response Surface Models Genetic Algorithm. Specific Energy Absorption (SEA) Crash Force Efficiency (CFE) are used in since these criteria important indicators for evaluating performance. Length thickness three as well radius one tube adopted design variables which effective parameters on SEA CFE. To reduce the computational cost procedure,...
The purpose of this study is to examine the energy absorption characteristics two different auxetic honeycombs that have negative Poisson's ratio (NPR) subjected an axial quasi-static load. total mass and volume are kept nearly equal. As load-extension graphs examined, it observed a smooth transition peak forces during crush for second one which has more strut. On other hand, first better capability.
The purpose of this study is to examine the energy absorption characteristics stepped concentric crash tubes subjected an axial impact load. with circular cross section are analyzed numerically by using LS-DYNA. total mass and volume kept constant when number increased. As increased, it observed a smooth transition peak forces during impact. Also increasing reduces maximum force leads reduction initial due lower wall thickness tubes.
Bio-based composites have gained higher importance due to their low-cost, recycling and moderate mechanical properties. Engineering structures under blast, crush other different pressure loadings can be manufactured using materials such as sisal based bio composites. In this study, fiber reinforced plastics numerically been investigated singular repeated blast effects. To make a prediction for experimental procedures in next phase, LS-DYNA modeling capabilities has investigated. For purpose,...
