Dynamic shear band propagation and failure in AISI 4340 steel
Abstract
Failure of metals and their alloys at high strain-rates is usually preceded by formation of adiabatic shear bands, along which cracks can easily nucleate and rapidly propagate causing fracture. In this study, adiabatic shearing and its effect on fracture behavior of AISI 4340 steel at high compressive strain-rate of about 1.9×103s−1 was investigated. Cracking was initiated by formation of micropores during adiabatic heating and thermal …
