Computational homogenization analysis in finite plasticity Simulation of texture development in polycrystalline materials
TL;DR: In this paper, the deformation of a micro-structure is coupled with the local deformation at a typical material point of the macro-continuum by three alternative constraints of the microscopic fluctuation field.

Computational modelling of single crystals
Alberto M. Cuitiño,Michael Ortiz +1 more
TL;DR: In this paper, a statistical mechanical model of dislocation motion through forest dislocations is formulated, where the strength of the short-range obstacles introduced by the forest dislocations is allowed to depend on the mode of interaction.

Formulation of implicit finite element methods for multiplicative finite deformation plasticity
TL;DR: In this paper, an implicit finite element formulation of the rate tangent modulus method is derived for which the consistent tangents, resulting in quadratic convergence of the equilibrium iterations, can be written out in closed form for arbitrary material models.

Multiscale modeling of the plasticity in an aluminum single crystal
TL;DR: In this paper, a hierarchical multiscale modeling methodology involving two distinct bridges over three different length scales is proposed to predict the work hardening of face centered cubic crystals in the absence of physical experiments.

Historical review of internal state variable theory for inelasticity
TL;DR: A review of the development and usages of internal state variable (ISV) theory is presented in this article, where the history of different developments leading up to the formulation of the watershed paper by Coleman and Gurtin is discussed.

The Continuum Theory of Lattice Defects
TL;DR: In this paper, the authors present a discussion on the continuum theory of lattice defects, which is the usual theory of elasticity modified to include internal stress, and discuss some of the background principles and illustrates them by specific examples.

Entropy Factors for Thermally Activated Unpinning of Dislocations
TL;DR: In this paper, the authors derived the entropy and effective jump frequency for the thermally activated unpinning of dislocations by using the statistical mechanics treatment of absolute rate theory, and showed that the entropy is very large for long loop lengths.
