Constitutive model for high strain rate response of polymeric composites

A constitutive model for characterizing high strain rate response of polymeric composites was developed using off-axis composite specimens. The difference in the results of coupon and block specimens was experimentally demonstrated and discussed. Off-axis block specimens were tested in compression at three different strain rates, 10−4/s, 10−2/s, and 1/s. Based on these experimental data, a viscoplasticity model was established to describe the...
