Abstract

Strain-rate effects are included in an effort to provide data for better utilization of material in press-forming applications through material property optimization. Uniaxial tensile tests were conducted on aluminum-killed and rimmed SAE 1008 sheet steel at strain-rates up to 102 per sec. Yield, flow stress, and pct total elongation are found to be very sensitive to strain-rate, but the strain-hardening exponent and anisotropy coefficient both show only slight changes. Calculations using strain-rate insensitive and strain-rate dependent constitutive equations investigated the effect of anisotropy, strain hardening, and strain rate on two in-plane stretch problems. The effect of each of these parameters is found to depend on the type of stretch.
