Abstract

An experimental investigation is conducted to evaluate the thermo-mechanical constitutive behavior of a TiB/Ti functionally graded material (FGM) under dynamic loading. A Split Hopkinson Pressure Bar (SHPB) apparatus with infrared (IR) spot heaters is used to investigate the effect of temperature on the mechanical behavior of FGM materials. A series of experiments are conducted at different temperatures and the stress strain relation for different strain rates are obtained. The material showed high thermal softening at elevated temperature resulting in a large reduction in compressive strength and an increase in failure strain. © 2008 Society for Experimental Mechanics Inc.
