抄録: Abstract:Compressive loading tests using acrylic acid resin and mortar specimens are performed to research the fracture of materials with a macroscopic discontinuity under the compression loading in this study. Crack surface has the half area of the cross-section area in a specimen and the specimen shapes that can produce mode Ⅱ and mode Ⅲ deformation are used. The fracture takes place after crack is closed, that is, the each crack surfaces are contacted. As a result, the fracture under mode Ⅱ deformation depends on a well-known wing crack for all specimens. In the experiments under mode Ⅲ deformation using mortar specimens, the fracture surfaces include partly the fracture surface along the initial crack surface. But almost fracture surfaces are made by the fracture pieces related to the splitting. In the experiments with an acrylic acid resin specimens, the fracture near the crack tip has the coarse surface. Therefore, the complicated stress condition near the crack tip is predicted.
