The inelastic deformation behavior of PMR-15 neat resin, a high-temperature polymer, was investigated at 260 -C. The experimental program was designed to explore the influence of strain rate on loading and unloading behaviors. In addition, the effect of prior strain rate on creep, relaxation, and recovery responses was evaluated. The material exhibits positive, nonlinear strain rate sensitivity in monotonic loading. Early failures occur before inelastic flow is fully established. The creep, relaxation, and recovery responses are significantly influenced by prior strain rate. The experimental d...
