Nonlinear Analysis of Cavities in Rock Salt

Ottosen, Niels Saabye LU and Krenk, Steen (1979) In Int. Journal of Rock Mechanics and Mining Science 16(4). p.245-252
Abstract
The paper covers some material and computational aspects of the rock mechanics of leached cavities in salt. A material model is presented in which the instantaneous stiffness of the salt is obtained by interpolation between the unloaded state and a relevant failure state. The model enables prediction of short term triaxial behaviour from uniaxial stress-strain curves. Key results from a nonlinear finite element calculation of a gas-filled cavity are given, and the general features are related to a simple nonlinear method of stress evaluation.
