摘要
基于视觉技术采用方形网格法进行变形区域塑性主应变分布测量.分析了其原理、特点以及根据节点位移计算塑性主应变的相关理论和方法.
A squareness grid method was used to determine the principal plastic strain distribution in a deformed area of a sheet metal piece. The paper describes the theoretical principles, the grid patterns and their characteristics, and the calculation of the principal strains based on the grid node displacements
