围道法是一种用于绘制工程结构残余应力的机械测量技术。它于2000年首次引入[1，2]，它依赖于新切割平面上应力松弛导致的表面变形来计算切割前部件中存在的残余应力。等值线法的主要优点是它能够产生垂直于切割表面作用的残余应力的2-D图。其他机械技术，如钻孔，深孔钻，层去除和切割，产生单一的残余应力线轮廓。等高线法的典型不确定度对于钢约为30 MPa，对于铝约为10 MPa [3]。
The contour method is a mechanical measurement technique for mapping residual stresses in engineering structures. First introduced in 2000 [1, 2], it relies on the surface deformation that results from stress relaxation over a newly cut plane to calculate the residual stresses that existed in the component before the cut. The main advantage of the contour method is its ability to produce a 2-D map of residual stress acting normal to the cut surface. Other mechanical techniques, such as hole drilling, deep hole drilling, layer removal and slitting, produce single residual stress line profiles. The typical uncertainty for the Contour Method is around 30 MPa for steel and 10 MPa for aluminium [3].
