TL;DR: In this article, a 3D microstructural reconstructions of steel crack-tip process zones are obtained and implemented into a large-scale simulation for ductile fracture analysis, and a quantitative understanding of the microvoid sheeting mechanism and mixed-mode failure controlling the zig-zag fracture surface is presented using the modeling technique utilized in this paper.

Reduced crack growth ductility due to asymmetric configurations
TL;DR: In this article, the authors show that the corresponding crack growth ductility is less with asymmetric configurations, than with the symmetric ones usually studied, and that cracks on a microscopic scale tend to become rough, to zig-zag, or even to spiral.

Microstructural simulation of adiabatic shear band formation in AISI 4340 steel using Voronoi Tessellation
Ioannis Polyzois,Nabil Bassim +1 more
TL;DR: In this paper, 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.
