Inelastic Deformation and Strength Degradation in Shocked Geologic Solids
Abstract
Two research tasks were initiated in this project. In the first, preliminary calculations were carried out to examine the response of miniature ruby gauges in metallic targets subject to axisymmetric loading. Although the initial results were encouraging, the calculational effort was discontinued because funding changes by AFOSR did not permit experimental work in this project. In the second task, the development of a damage model was undertaken to describe the shock wave response of a brittle solid. In particular, the focus was on model development to describe both the loading and unloading response in a consistent manner. Preliminary results are encouraging and many features observed in the experimental data are simulated. at least qualitatively, by the model.
