PLASTER OF PARIS AS A STATIC AND DYNAMIC MODEL TESTING MATERIAL

Abstract

Plaster of Paris and highgrade pottery plaster have been used for over thirty years as a modelling material. In the field of experimental study of elastic stresses with models, plaster has been a desirable material because of its ease of casting into any desired shape, its linear stress-strain relation up to fracture, its low modulus of elasticity and fracture strength, and its small grain size. Its linear stress-strain characteristics up to fracture and high compressive strength in comparison to its tensile strength have made it a desirable material to be used in the brittle-model method of stress analysis. When plaster models are used for the estimation of stress in a certain elastic structure, it is usually termed as the plaster-model method.
