Hydrogen embrittlement is a multifaceted phenomenon that can significantly compromise the toughness of susceptible metals. We study the critical process of hydrogen diffusion within the body-centered cubic lattice of iron (BCC-Fe or α−Fe) using ab

The flow stress behaviour of a directionally solidified nickel-base superalloy, MAR-M247, is presented through the combination of experiments and crystal-plasticity simulations. The experimental campaign encompassed quasi-static and dynamic testing i

A microstructure-sensitive fatigue life prediction framework based on CP-FFT is proposed to study SLM fabricated Hastelloy-X. The microstructure enters in the model through the shape, size and orientation distributions of grains in the RVEs, which ar

The deformation of crystalline materials by dislocation motion takes place in discrete amounts determined by the Burgers vector. Dislocations may move individually or in bundles, potentially giving rise to intermittent slip. This confers plastic defo

A method based on the Fast Fourier Transform is proposed to obtain the dispersion relation of acoustic waves in heterogeneous periodic media with arbitrary microstructures. The microstructure is explicitly considered using a voxelized Representative

A novel approach has been developed to estimate fatigue life at the specimen/component level from the simulation of relatively small Representative Volume Elements (RVE) of the polycrystalline microstructure. This technique estimates the statistical

The Kobayashi–Warren–Carter (KWC) phase-field model was originally conceived for two-dimensional systems to model grain boundary migration and grain rotation, which play a crucial role in nanocrystalline materials, and in phenomena such as superp
