ABSTRACT
We performed split Hopkinson bar (SHB) tests, Taylor impact tests, and dynamic bend tests on 91%W-6%Ni-3%Co alloys to characterize strain-rate effects on stress-strain behavior. Materials from two manufacturers were tested. The fracture process of this material was examined. This alloy shows no appreciable work or strain-rate hardening at high strain rates. The dynamic flow stress was 2.2 ± .3 GPa.

    Failure during sheared edge stretching of sheet steels is a serious concern, especially in advanced high-strength steel (AHSS) grades. The shearing process produces a shear face and a zone of deformation behind the shear face, which is the shear-affected zone (SAZ). A failure during sheared edge...

    To account for the physical mechanisms of failure, the concept of thermal activation of damage and failure has been adopted as basis for this material model development. This basic assumption makes the proposed approach compatible with the Mechanical Threshold Stress (MTS) model, which was used...
