Abstract
This paper outlines an experimental and computaional study of constitutive relations of rocks, including sandstone,granite, and limestone. Plate impact experiments were conducted by means of a gas gun. A Lagrangian analysis presents for a series of stress histories. The procedure for fitting a stress time distance surface is described. From fitted surface are obtained the derivatives of the flow variables. Mechanical properties and deformation characteristics of rocks under strong impact loading are analysed.
