双边切口薄板小试件动态弹塑性有限元分析

ELASTIC-PLASTIC ANALYSIS OF A DYNAMICALLY LOADED DOUBLE NOTCH THIN PLATE

  • 摘要:对[1]中采用的双边切口薄板小试件进行了动态弹塑性有限元分析,计算了动态积分,研究论证了积分作为该试验系统试件裂端表征参量的可行性;对深裂纹Rice公式计算动态积分的有效性进行了验证。为文[1]提出的平面应力型动态弹塑性起裂韧度的表征与测试方法提供了进一步的论证。

    Abstract:In this paper,dynamic elastic-plastic FEM analyses of a double notch thir plate subjected to the experimentally measured tensile pulse are presented.An invariant finite domain integral expression J(t)employed as dynamic energy release rate is calculated. The analysis demonstrate that J(t)integral can be regarded as the crack tip characterizing parameter for the double notch specimen used in Ref.1. we also calculate the value of the J_(dc)(t)integral from the measured load-calculated displacement curve by us...
