Current high strain rate testing techniques typically rely on the split‐Hopkinson bar (SHB). The early response in an SHB test is corrupted by inertia making it difficult to accurately characterise the transition from elasticity to plasticity for metals. Therefore, a new test method is required. This article is the second in a two‐part series which aims at developing a new high strain rate test for elasto‐plasticity identification using the image‐based inertial impact (IBII) method. The goal of this article is to validate the new method experimentally using IBII tests on aluminium 6082‐T6 (minimal rate sensitivity) and stainless steel 316L (rate sensitive). Comparison of the quasi‐static and dynamic stress–strain curves for the aluminium case showed minimal difference providing experimental validation of the method. The same comparison for the steel showed that the method was able to detect rate sensitivity.

使用基于图像的惯性冲击（IBII）测试第2部分，进行高应变率弹塑性识别：实验验证

当前的高应变率测试技术通常依赖于分裂霍普金森棒（SHB）。SHB测试中的早期响应被惯性破坏，因此很难准确地描述金属从弹性到可塑性的转变。因此，需要一种新的测试方法。本文是由两部分组成的系列文章中的第二篇，该系列文章旨在使用基于图像的惯性冲击（IBII）方法开发一种新的高应变速率测试，以用于弹塑性识别。本文的目的是通过对铝6082-T6（最小速率敏感度）和316L不锈钢（速率敏感度）进行IBII测试，以实验方式验证该新方法。铝箱的准静态和动态应力-应变曲线的比较显示出最小的差异，提供了该方法的实验验证。
