Journal ArticleDOI
Large simple shear and torsion problems in kinematic hardening elasto-plasticity with logarithmic rate
TL;DR: In this article, the authors used the self-consistent kinematic hardening J 2 -flow model based on the logarithmic tensor rate to study stress responses to simple simple shear and torsional deformations in elastoplastic bodies.
Journal ArticleDOI
Finite Bending of a Rectangular Block of an Elastic Hencky Material
TL;DR: In this paper, a closed-form solution for the bending angle and the bending moment in terms of the maximum or minimum circumferential stretch in a general case of compressible deformations for any assigned stretch normal to the bending plane is presented.
Journal ArticleDOI
Large strain responses of elastic-perfect plasticity and kinematic hardening plasticity with the logarithmic rate: Swift effect in torsion
TL;DR: In this article, a new Eulerian rate type elastic-perfectly plastic model has been established by utilizing the newly discovered logarithmic rate, and the finite simple shear response has been studied and shown to be reasonable for both shear and normal stress components.
Journal ArticleDOI
Effective 3D failure simulations by combining the advantages of embedded Strong Discontinuity Approaches and classical interface elements
TL;DR: It is shown that several simultaneously active discontinuities in each finite element are required to capture highly localized material failure.
Journal ArticleDOI
Some basic issues in traditional Eulerian formulations of finite elastoplasticity
TL;DR: In this article, the authors introduced the notion of an Eulerian type rotation-conjugate group of the initial material symmetry group and derived plastic consistency conditions for hardening, softening, and perfectly plastic behaviour.
