ABSTRACT

ABSTRACT: Stress-related probability distribution functions are determined for the random variable material model parameters of the Munson-Dawson multi-mechanism deformation creep model for salt These functions are obtained indirectly from experimental creep data for clean salt. The parameter distribution functions will form the basis for numerical calculations to generate an appropriate distribution function for room closure. Also included is a table that gives the values of the parameters for individual specimens of clean salt under different stresses.
