This paper describes the experimental results and the theoretical analysis concerning the size effects on fractures of plaster thin-walled and solid cylinders with a transverse hole under compression. The distribution of stresses around the hole is analyzed by the effect of the surface layer. The analytical results coincide well with the experimental data and are concluded as follows. (1) There are two types of fractures, depending on the diameter of the hole, one is the fracture occurring due to the compressive stress and the other is that caused by the tensile stress. (2) The fracture stress of the thin-walled cylinder depends on only the diameter of the hole. (3) The fracture stress of the solid cylinder is influenced not only by the diameter ratio of the hole to the test cylinder, but also by the diameter of the cylinder.
