Microstructural simulation of adiabatic shear band formation in AISI 4340 steel using Voronoi Tessellation

Using the stress strain response data obtained from an experimental investigation carried out by the first author (Polyzois, 2014), a finite element model was developed in Matlab and explicit FEA software ANSYS and LSDYNA to simulate Adiabatic Shear Band (ASB) formation in AISI 4340 steel on the microstructural level under high strain rate impact. This FEA model uses the Voronoi Tessellation to generate geometry simulating the microstructure of …
