Plastic behavior and failure mechanism of Ti-6Al-4V under quasi-static and dynamic shear loading

A new kind of double-shear specimen (DSS) is used to study quasi-static and dynamic behaviors of Ti-6Al-4V under simple shear conditions. With different loading techniques, a wide range of shear strain rates are covered from 0.002 s−1 to 60,000 s−1. The flow stress curves are determined under different conditions. It's observed that the work-hardening effect on the flow stress is weakened gradually with the increasing strain rates. Both the...
