The paper describes the experimental results and the theoretical analysis concerning the fractures of plaster hollow cylinders with a transverse hole under compression. This analysis has been carried out with the surface layer theory applied to the stresses around the circular hole in a strip under compression. The analytical results coincide well with the experimental data and the conclusions are as follows: (1)There are two types of fractures, categorized depending on the diameter of the hole; one is the fracture caused by compressive stress and the other is that caused by the tensile stress. (2)The fracture stresses of the hollow cylinders are influenced not only by the diameter of the hole, but also by the ratio of inner to outer diameter of the cylinder. (3) The thickness of the surface layer of the plaster in 0.25mm
