云纹干涉法是研究复合材料变形的一种有效方法.本文讨论了用云纹干涉法测量复合材料的固化残余应变,获得了试件表面的位移条纹图,并用电测方法加以验证。
Moiré interferometry is an effective method to study the deformation of composite materials.This paper discusses the measurement of the residual strain of the composite material by moiré interference method and the displacement fringe pattern on the surface of the specimen, which is verified by the electrical measurement method.
