摘要
The dynamic response of four types of stainless steel sheet was investigated at different strain rates from 10(-2) up to 10(3) s(-1). The results from the tensile tests were used to evaluate the parameters in three different multiplicative strain rate equations of the type used in crashworthiness calculations. A new type of sigmoid constitutive equation is proposed for one grade of stainless steel.
