The multiaxial large deformation and ductile fracture behavior of laser powder bed fusion (L-PBF) additively manufactured austenitic 316L stainless steel was experimentally measured. Data from tests in two orientations, under five dissimilar stress s

To reduce reliance on experimental fitting data within the crystal plasticity finite element method (CPFEM), an approached is proposed that integrates first-principles calculations based on density functional theory (DFT) to predict the strain harden

Nickel aluminide $(\mathrm{N}{\mathrm{i}}_{3}\mathrm{Al})$ is an important material for a number of applications, especially when used as a strengthening constituent in high-temperature Ni-based superalloys. Despite this, there is minimal information

The stress state dependent fracture behavior of DP600 was investigated using a representative volume element (RVE) based finite element model. To simulate fracture at the microscale, fracture models for ferrite and martensite were incorporated into t

In dual phase (DP) steels, fracture can initiate within the ferrite phase, the martensite phase, or at the interfaces between these phases with the dominant fracture initiation mechanism expected to depend on a number of factors, including the phase
