哑铃状扁平形试件拉伸试验圆角误差分析

Error Caused by Flat Dumbbell-shaped Specimen Fillet in Tensile Test

运用ANSYS软件基于AUTODYN平台对动态拉伸试验进行数值仿真,分析由于圆角的存在给哑铃状试件中应力均匀性带来的影响,从数值仿真的角度为处理试验结果提供参考。

Based on AUTODYN platform,the numerical simulation of a tensile test is conducted by use of ANSYS software,to analyze the influence of the rounded corners of specimen on the stress uniformity,to provide a reference for processing test data from the perspective of numerical simulation.
