Abstract
Abstract： Based on the principle of linear superposition, a nondestructive measurement for residual stresses, i.e. the loading measurement method for residual stresses was proposed. In a certain way, it applies loads on the injectionmolded part, measures the strain on the surface measuring points, and calculates the loading stresses and residual stresses on the measuring points of the injectionmolded 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.
