Modeling of Ultrahigh Molecular Weight Polyethylene Single Fiber Failure Under Dynamic Multiaxial Transverse Loading
Journal of Dynamic Behavior of Materials - - 2022
This study investigates the failure of microscale Dyneema® SK76 ultrahigh molecular weight polyethylene single fiber subjected to dynamic multiaxial transverse loading by three impactor geometries of radii – 200 (blunt), 20 (sharp), and 2 (razor) µm. A 3D finite element model of the single fiber transverse impact experiments by Thomas et al. 2020 has been developed to investigate the deformation a...... hiện toàn bộ
A Comparative Study on the Ballistic Performance and Failure Mechanisms of High-Nitrogen Steel and RHA Steel Against Tungsten Heavy Alloy Penetrators
Journal of Dynamic Behavior of Materials - - 2020
Traditionally, medium-carbon, low-alloy steels with tempered martensitic microstructures are widely used in structural armor applications. There have been continuous attempts to develop alternative structural armor materials that can provide further weight reduction of armored vehicles. In this context, high-nitrogen steel (HNS) plates with austenitic microstructures were studied against a full-sc...... hiện toàn bộ
Generalized Stress–Strain Curves for IBII Tests on Isotropic and Orthotropic Materials
Journal of Dynamic Behavior of Materials - Tập 5 - Trang 180-193 - 2019
This article presents a particular use of the Virtual Fields Method to exploit the results of Image-Based Inertial Impact (IBII) tests. This test consists on an edge-on impact of a free-standing thin flat rectangular coupon. The specimen response is recorded using an ultra-high speed camera filming the deformation of a grid pattern printed at its surface. From these images, displacement fields are...... hiện toàn bộ
Shock Response of Polymethyl Methacrylate (PMMA) Under Explosive LoadingAbstract The dynamic response of polymethyl methacrylate (PMMA) is well understood for one-dimensional planar impact shocks, but limited research has been performed on the response of PMMA under spherical shock loading. In this work, the shock decay of an explosively-driven shock wave into PMMA was experimentally measured. PMMA cubes of various geometries were explo... ... hiện toàn bộ

Shock Wave Perturbation Decay in Granular Materials
Journal of Dynamic Behavior of Materials - Tập 1 - Trang 370-387 - 2015
A technique in which the evolution of a perturbation in a shock wave front is monitored as it travels through a sample is applied to granular materials. Although the approach was originally conceived as a way to measure the viscosity of the sample, here it is utilized as a means to probe the deviatoric strength of the material. Initial results for a tungsten carbide powder are presented that demon...... hiện toàn bộ

The Effect of Liquid Tamping Media on the Growth of Richtmyer–Meshkov Instability in Copper
Journal of Dynamic Behavior of Materials - Tập 7 - Trang 338-351 - 2021
The Richtmyer–Meshkov instability (RMI) arises at an impulsively accelerated interface between two materials of different density. Historically, this instability was studied in fluids. Recently, RMI studies have been extended to investigate material properties of solids. Material strength at high strain-rates in solids have been extracted from the amplitude and growth of the RMI spike in an untamp...... hiện toàn bộ
Deformation and Failure Mechanisms in a Magnesium Alloy Under Uniaxial Compressive Loading
Journal of Dynamic Behavior of Materials - Tập 6 - Trang 303-316 - 2020
We have investigated the deformation and failure mechanisms of a rolled AZ31B magnesium alloy under both quasi-static (
$$10^{-3}\,{\text {to}}\,10^{-2}\,{\text{s}}^{-1}$$
) and dynamic (
$$10^{3}\,{\text{s}}^{-1}$$
) compressive loading. The observed anisotropy in the plastic response originates from the different in-plane and out-of-plane deformation mechanisms activated when the loading orien...... hiện toàn bộ
