High resolution computer simulations of manganin gauges mounted to measure lateral stresses in a steel matrix subject to nominally 1-D shock have been run using the AWE Eulerian code Shamrock. The components of the stress and strain in each of the cells in the manganin element have been obtained from the code. Piezoresistive and plastic strain coefficients derived by previous workers have been used to compute the resistivity of each cell in the gauge and, ultimately, the total resistance change of the gauge. The predicted resistance changes are compared with existing experimental data.
