TL;DR: In this article, a mathematical model for a finite-strain elastoplastic evolution problem is proposed in which one time-step of an implicit time-discretization leads to generally non-convex minimization problems.
Abstract: A mathematical model for a finite–strain elastoplastic evolution problem is proposed in which one time–step of an implicit time–discretization leads to generally non–convex minimization problems. The elimination of all internal variables enables a mathematical and numerical analysis of a reduced problem within the general framework of calculus of variations and nonlinear partial differential equations. The results for a single slip–system and von Mises plasticity illustrate that finite–strain elastoplasticity generates reduced problems with non–quasiconvex energy densities and so allows for non–attainment of energy minimizers and microstructures.

TL;DR: A maximum principal strain criterion can be defined a suitable candidate for the in vivo risk factor assessment on long bones by correctly identifying the level of failure risk and the location of fracture onset in all the modelled specimens.

TL;DR: In this paper, the yield strength of Pd40Ni40P20 metallic glass undergoing low-temperature, localised plastic flow has been measured in uniaxial compression, plane-strain compression, pure shear and tension.

TL;DR: In this article, the Taylor factor with a value of 3.06 is the correct parameter to apply in such work, based on an inappropriate application of the von Mises and Tresca yield criteria.

TL;DR: In this article, a method for the incremental elastic-plastic analysis of two-dimensional stress systems (plane stress, plane strain and axisymmetrically loaded body of revolution) is described.
