摘要：

Plaster of Paris is a brittle, porous solid, easy to shape, which has potential as a model material for the study of brittle, porous, solids such as ceramics, rocks and cement. This paper describes the mechanical properties of plaster of Paris - modulus, strength, fracture toughness, etc. - as a function of porosity, The material is then used to study the initiation and propagation of cracks in compression, as a function of porosity, stress state and stress concentration.
