Abstract Scope |
Composites comprising multiple dissimilar phases have recently seen increased interest for high strain rate applications. During high rate loading, stress is non-uniformly distributed and travels in waves. The character of those waves within and when transferring between phases is dictated by the properties of the constituents. Here we discuss effects of constituent properties and mismatches in properties on the nature of propagating stress waves in multiphase materials. In particular, elastic wave speeds are found to be dominated by the major phase and mismatches in properties lead to stress transfer by shear between phases. Phase boundary discontinuities and plasticity introduce further complexities which can dramatically alter stresses as the waves interact with interfaces. |
