A new integration algorithm for finite strain J2 plasticity based on midpoint rule
Midpoint and double step algorithms are interesting implicit algorithms for integrating the governing equations in plastic regime. Developing such algorithms for large deformation is complex due to the various configurations that have to be considered. In this paper a new algorithm is proposed for the integration of governig equations in large deformation plasticity which is based on midpoint rule. The time continuous model as well as algorithmic setup are discussed in details.

Postdoc at the University of Lyon (France) in atomistic modeling of crystalline plasticity
Applications are invited for a postdoctoral position at the Institut Lumière Matière of the University of Lyon in France to simulate by MD in controlled geometries the interactions between dislocations and general "dirty" grain boundaries. This work is part of an EU project on fatigue deformation involving France, Germany and Belgium. Details by contacting david.rodney [at] univ-lyon1.fr, or visit http://ilm-perso.univ-lyon1.fr/~drodney/.

Geometric nonlinear thermoelasticity and the time evolution of thermal stresses
In this paper we formulate a geometric theory of nonlinear thermoelasticity that can be used to calculate the time evolution of the temperature and thermal stress fields in a nonlinear elastic body. In particular, this formulation can be used to calculate residual thermal stresses. In this theory the material manifold (natural stress-free configuration of the body) is a Riemannian manifold with a temperature-dependent metric. Evolution of the geometry of the material manifold is governed by a generalized heat equation.

Sampling data from large numerical simulations
Large numerical simulations lead to large data sets that typically need some sampling to make analysis tractable. Check out my upcoming series of posts on the topic at http://www.parresianz.com//sampling/latin_hypercube_sampling/
