TL;DR: In this article, a two-dimensional numerical model was developed to simulate the evolution of grain structure observed during the laser additive manufacturing process, where a cellular automata method was used to describe grain growth and the Goldak heat source model was adopted to calculate the heat input during laser melting.

TL;DR: In this paper, a numerical analysis of the reinforcement particle shape and interface strength effects on the deformation and fracture behavior of an Al/Al2O3 composite is performed, and it is shown that microstructural heterogeneity of the composite gives rise to a complex stress-strain state in the vicinity of particle boundaries and hence to near-interface areas undergoing tensile deformation both in tension and compression.

TL;DR: In this article, a 3D numerical analysis of mesoscale surface roughening in a polycrystalline aluminum alloy under uniaxial tension has been performed.

TL;DR: In this paper, a hierarchical model for deformation and fracture at the micro-, meso-and macro-level for metals and composites is presented. But the authors focus on unifying the method of approach to be supported by tests and calculations.

TL;DR: In this paper, the problem of multiscale surface roughening in commercial purity titanium subjected to uniaxial tension is addressed, and a 3D polycrystalline model with explicit consideration of grain structure is presented.
