摘要

能够承受高应变率和/或冲击载荷的意外事件的结构工程设计需要预测建模能力,以便在绝热剪切带(ASB)之后在数值上再现潜在的过早破坏。本章的目的是回顾文献中可用的面向asb的建模方法(而不是假装详尽),这些方法可以更好地理解绝热剪切带及其在结构金属和合金中的后果。

Some Issues Related to the Modeling of Dynamic Shear Localization-assisted Failure
Engineering design of structures that will withstand accidental events involving high strain rate and/or impact loading requires predictive modeling capabilities for reproducing numerically potential premature failure following adiabatic shear banding (ASB). The purpose of the present Chapter is to review ASB-oriented modeling approaches available in literature (while not pretending to be exhaustive) that provide a better understanding of adiabatic shear banding and its consequences in structural metals and alloys.
