Journal ArticleDOI
A constitutive model for plastically anisotropic solids with non-spherical voids
TL;DR: In this paper, a variational principle is formulated for the yield criterion of the effective medium and specialized to a spheroidal representative volume element containing a confocal sgeroidal void and subjected to uniform boundary deformation.
Journal ArticleDOI
On the path-dependence of the fracture locus in ductile materials - Analysis
TL;DR: In this paper, the effect of loading path on the fracture locus was examined theoretically by means of cell model calculations, and it was found that the failure locus for nonradial loadings differs substantially from that for radial paths.
Journal ArticleDOI
Power-Law Creep from Discrete Dislocation Dynamics
TL;DR: Two-dimensional discrete dislocation dynamics simulations of combined dislocation glide and climb leading to "power-law" creep in a model aluminum crystal are reported, indicating that the underlying physics is well captured.
Journal ArticleDOI
Work hardening in micropillar compression: In situ experiments and modeling
Daniel Kiener,Daniel Kiener,P. J. Guruprasad,S.M. Keralavarma,Gerhard Dehm,Gerhard Dehm,A. Amine Benzerga +6 more
TL;DR: In this article, the authors compared experimental measurements and simulation results for the evolution of plastic deformation and hardening in micropillars and employed physics-based constitutive rules for an adequate representation of hardening.
Journal ArticleDOI
Void growth and coalescence in anisotropic plastic solids
TL;DR: In this article, large strain finite element calculations of unit cells subjected to triaxial axisymmetric loadings are presented for plastically orthotropic materials containing a periodic distribution of aligned spheroidal voids.
