摘要：
The paper describes an algorithm of photoelastic tomography and its application for residual stress measurement in algorithm is based on a linearized solution of the equations of integrated,,lass articles of complicated shape. The photoelasticity. The problem of tensor field tomography is decomposed into several problems of scalar field tomography for normal stress components of the stress tensor. The method is implemented with an automated polariscope supplied with a rotary stage. Several examples illustrate application of the method.
