Abstract
The results of an earlier paper are extended to include strain hardening in the analytic model for piezoresistance. This development is necessary to model the gauge hysteresis observed in the experimental data. Analytic developments to incorporate strain hardening in the theoretical formalism and procedures to calculate the gauge response are described. The analytic model is used to calculate the response of ytterbium (Yb) foils in a polymethylmethacrylate matrix in both shock wave and quasi-static experiments. Good agreement is observed between the model predictions and experimental results. Difficulties in calculating the lateral gauge response when the matrix material is inelastic are discussed.This publication has 12 references indexed in Scilit:
