Abstract:

A simple qualitative model is developed for the existence of a precursor memory effect. By using our model we investigate Taylors prediction of a memory in Armco iron and conclude that his theory leading to the memory prediction is incomplete in that it neglects viscous effects occurring in the precursor shock front region and plasticity contributions to the stress. When such effects are incorporated into the theory the amount of memory is shown to be diminished. Author
