Journal ArticleDOI
A computational framework for brittle crack-propagation based on efficient virtual element method
Ali Hussein,Fadi Aldakheel,Blaž Hudobivnik,Peter Wriggers,Pierre-Alain Guidault,Olivier Allix +5 more
TL;DR: An efficient low order virtual element method (VEM) for crack propagation in elastic solids at small strains is outlined within this work as mentioned in this paper, which is a competitive discretization scheme for meshes with highly irregular shaped elements and arbitrary number of nodes.
Journal ArticleDOI
Numerical derivation of contact mechanics interface laws using a finite element approach for large 3D deformation
TL;DR: In this paper, a homogenization method is presented to obtain by numerical simulation interface laws for normal contact pressure based on statistical surface models, assuming elastic behaviour of the asperities, the interface law of Kragelsky et al. (Friction and Wear-Calculation Methods, Pergamon, 1982) is chosen for comparison.
Journal ArticleDOI
A finite element method for stability problems in finite elasticity
Stefanie Reese,Peter Wriggers +1 more
TL;DR: In this article, a finite element method is developed to treat stability problems in finite elasticity, where constitutive equations are formulated in principal stretches, which allows a general representation of the derivatives of the strain energy function with respect to the principal stretches.
Journal ArticleDOI
3D multiscale crack propagation using the XFEM applied to a gas turbine blade
TL;DR: In this paper, a multiscale technique to investigate advancing cracks in 3D space is presented. But the authors focus on the fine-scale domain, i.e., where stress concentrations and high stress gradients occur.
Journal ArticleDOI
Generating virtual process maps of SLM using powder-scale SPH simulations
TL;DR: A smoothed particle hydrodynamics (SPH) implementation on GPU, the 3D melt pool dynamics in a single laser track can be simulated within less than an hour with a reasonable spatial resolution, an extreme speedup compared to concurrent CFD methods that have recently been applied to the same problem.
