Numerical simulation is usually used for predicting the response of concrete and fiber reinforced structures to blast or impact loads. Depending on both charge weight standoff distance, loads can cause fracture spalling concrete. In order numerically reproduce these effects, an erosion model be remove from calculation elements that have reached certain criteria. This represents a numerical tool avoid great distortion Lagrange meshes. For this reason, its application physical phenomenon...
A cohesive zone model implemented in an augmented Lagrangian functional is used for simulation of meso-scale fracture problems this paper. The method originally developed by Lorentz first presented a rigorous variational framework. equivalence between the stationary point one-field problem and saddle mixed formulation proved solving double inequality functional. An adaptation to simulate phenomena via mesh modification also as algorithm insert zero-thickness interface elements based on...
Compaction bands play a key role in the deformation processes of porous rocks and explain different aspects physical geological formations. The state-of-the-art description localized strains that lead to compaction banding has limitations from mechanical point view. Thus, we describe phenomenon using consistent axiomatic formulation. We build viscoplastic model minimal assumptions; base our on six principles study band strain localization triggered by viscous effects. analyze stress states...

A family of constitutive models for mine cemented backfill is presented. Four formulas the density- and pressure-dependency elastic moduli, five friction angle four age-dependency moduli effective cohesion are incorporated into an isotropic hypoelasticity with Mohr-Coulomb perfect plasticity framework implemented in PLAXIS as a user-defined material model. This includes standard Mohr-Coulomb, Bolton, Leps, Barton Hoek- Brown trivial cases when both nonlinear elasticity switched off. In this...
Recent failures of upstream-raised tailings storage facilities (TSF) raised con-cerns on the future use these dams. While being cost-effective, they entail higher risks than conventional dams, as stability largely relies strength tailings, which are loose and normally-consolidated materials that may exhibit strain-softening during un-drained loading. Current design practice involves limit equilibrium analyses adopting a fully-softened shear strength; while conservative, this neglects work...
We describe a phase-field model for the electrodeposition process that forms dendrites within metal-anode batteries. derive free energy functional model, arriving at system of partial differential equations evolution phase field, lithium-ion concentration, and an electric potential. formulate, discretize, solve set describing coupled electrochemical interactions during battery charge cycle using open-source finite element library. The library allows us to use parallel solvers time-marching...
