Abstract
In aircraft and automotive components, polymeric materials such as PMMA are subjected to dynamic loading and deform at moderate (1–100 s−1) and high strain rates (>102 s−1). A methodology for calculating the strain-rate dependent parameters of PMMA at high strain rates will be presented. Images of each sample deforming were collected during an inertial impact test with an ultra-high speed camera, recording at 3 Mfps. The full field displacement, strain, and acceleration were input to the virtual fields method to perform an inverse identification of the material parameters.
