Multi-Control-Volume Approach to Elastic and Plastic Waves in Layered Composites.

Abstract

A multi-control-volume method is developed to predict the wave velocities and stresses in the elastic and plastic regions of layered composities. From the method, the wave velocities and stresses may be calculated from the constitutive relation of its constituents. The interfacial shearing force may then be computed. Two composites Boron/Aluminum and Graphite/C-7 Epoxy have been used for sample calculations. The calculated wave velocities will differ from a constant as the impact velocity becomes large.
