A non-linear hardening model based on two coupled internal hardening variables: formulation and implementation [PDF]
, 2005 An elasto-plasticity model with coupled hardening variables of strain type is presented. In the theoretical framework of generalized associativity, the formulation of this model is based on the introduction of two hardening variables with a coupled ...

Mapping snow depth return levels: smooth spatial modeling versus station interpolation [PDF]
Hydrology and Earth System Sciences, 2010 For adequate risk management in mountainous countries, hazard maps for extreme snow events are needed. This requires the computation of spatial estimates of return levels. In this article we use recent developments in extreme value theory and compare two

Cycling chaotic attractors in two models for dynamics with invariant subspaces [PDF]
, 2004 Nonergodic attractors can robustly appear in symmetric systems as structurally stable cycles between saddle-type invariant sets. These saddles may be chaotic giving rise to 'cycling chaos'.
