Abstract:

Material response characterization is discussed from the viewpoint of its impact on the results obtained from free-field ground shock calculations. Selected field and laboratory test data are used in conjunction with calculational results to illustrate the influence of anisotropy, tension cutoff criteria, lithostatic stress fields, loading rate sensitivity, high pressure shear behavior, residual strength or post-failure response, and pore water pressure. The pitfalls involved in overgeneralization of geologic material property test results, reliance on data of limited type and source, and failure to understand the basic mechanisms contributing to observed responses are empahsized.
