摘要
介绍一种残余应力的测量新方法。标定试验结果表明，测点应变增量与残余应力间存在良好的线性关系。该方法应用于实际焊缝应力的测量取得了良好的效果。
A new method of measuring residual stresses was introduced in this paper.The experiment results show that the measured additional strain keep a linear relationship with residual stress in the structure.The experimental on residual stress of welding joints indicates that the longitudinal residual stress distribution can be obtained.
