摘要：

Based on the principle of linear superposition, a non-destructive measurement for residual stresses, i.e. the loading measurement method for residual stresses was proposed. In a certain way, it applies loads on the injection-molded part, measures the strain on the surface measuring points, and calculates the loading stresses and residual stresses on the measuring points of the injection-molded part. The results show that the loading measurement method has advantages over the hole drilling method and the layer removal method because it has a comparatively lower measuring cost, and it is precise when the loading state of the measured part is under the elastic range. © 2016, Editorial Board of Journal of Shanghai Jiao Tong University.
