ひずみ凍結法による押込み球圧子下の光塑性解析

Hardness test is one of the basic material testings. This investigates strain behavior in polycarbonate plate by loaded spherical indentator using the strain-freezing method to establish a method of evaluating the material properties of high polymer materials which have been widely used as machine parts and structural members because of a high elastic modulus and strength. As a result, the strain-freezing method was found to be effective for analyzing strains in polycarbonate by loaded spherical indentator. Furthermore, the relation between the photoelastic fringe order and principal strain difference is found to be proportional as well as the relation between the total strain.
