本文研究了韧性金属在动态载荷作用下的损伤与断裂行为。在[1-3]中提出的唯象连续损伤和断裂模型，考虑了材料的速率和温度依赖性，提供了合理的高应变率实验结果，而相应的材料参数的识别结果很难从现有的实验数据。这种信息的缺乏可以通过包含单元格的空隙的微机械数值模拟来解决。在这种情况下，动态微观力学模拟的结果，可用于研究损伤效应的微观尺度和验证率相关的连续损伤模型。（© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
The paper deals with the damage and fracture behavior of ductile metals under dynamic loading conditions. The in [1–3] presented phenomenological continuum damage and fracture model, which takes into account the rate‐ and temperature‐dependence of the material, provides reasonable results of experiments with high strain rates while the identification of the corresponding material parameters results difficult from the available experimental data. This lack of information can be resolved by micro‐mechanical numerical simulations of void containing unit‐cells. In this context results of dynamic micro‐mechanical simulations are presented which can be used to study the damage effects on the micro‐scale and to validate the rate‐dependent continuum damage model.
