Micromechanical Considerations in Shock Compression of Solids

Abstract

The application of what is commonly known as solid continuum mechanics has been very successful in descriptions of the shock-compression process. It has given us the jump conditions, useful concepts of average quantities such as density and specific internal energy (for example), and constitutive descriptions (including equations of state) involving these average quantities and their time rates of change. Even as we profitably use these ideas, we always have in mind micromechanical concepts such as the crystal lattice, the electronic structure of the crystallographic system, and lattice defects which give rise to important physical phenomena.
