A physical SNOWPACK model for the Swiss avalanche warning: Part I: numerical model
Perry Bartelt,Michael Lehning +1 more
TL;DR: In this paper, the numerical formulation of a one-dimensional physical snowpack model is presented, which is operationally employed on a day-to-day basis by avalanche warners to predict snowpack settlement, layering, surface energy exchange and mass balance.

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.

Modeling the Bauschinger effect for sheet metals, part I: theory
B.K. Chun,J.T. Jinn,J.K. Lee +2 more
TL;DR: In this paper, a combined nonlinear hardening model for time independent cyclic plasticity is examined and a simple modification is suggested for the isotropic part of the hardening rule to utilize the conventional tensile test data directly.

Meso-structural study of concrete fracture using interface elements. I: numerical model and tensile behavior
TL;DR: In this paper, a mesostructural model for the mechanical behavior of heterogeneous quasi-brittle materials is used systematically to analyze concrete specimens in 2D. The numerical model is based on the use of zero-thickness interface elements equipped with a normal-shear traction-separation constitutive law representing non-linear fracture, which may be considered a mixedmode generalization of Hillerborg's “Fictitious Crack Model.
Journal ArticleDOI
Stress-based nonlocal damage model
TL;DR: In this paper, a modification of the nonlocal integral regularization method that takes the stress state into account is proposed, which improves the numerical solution of problems observed in numerical simulations involving regularization techniques.
