High Strain Rate Behavior of Metals Ceramics, and Concrete

Abstract

This report summarizes the major results obtained during the contractual period between September 1986 through December 1990. During this period, high strain rate behavior of various metals and ceramics was investigated through a combined experimental and computational approach. The experiments include quasi-static, split Hopkinson bar, rod-on rod, plate-on-rod, and plate impact test configurations. Three-dimensional, loading history dependent, and internal state variable based constitutive models for metals and ceramics were developed. Damage, in terms of microvoids/cracks nucleation and growth, was treated as an internal state variable. The model constants for several metals and AD85 ceramic were determined and applied successfully to several impact problems. impact, constitutive equation, failure, model, high strain rate, metals, ceramics, concrete, computer code.
