Stabilized mixed finite elements for deformable porous media with double porosity
Coupled problem Double porosity Effective stress Mixture theory Stabilized finite elements Twofold saddle point problem
2015/7/1
Natural geomaterials such as fissured rocks and aggregated soils often exhibit a pore size distribution with two dominant pore scales, usually termed macropores and micropores. High-fidelity descripti...
Embedded strong discontinuity finite elements for fractured geomaterials with variable friction
bifurcation rate- and state-friction strong discontinuity enhanced strain finite element
2015/7/1
The strong discontinuity approach to modelling strain localization, combined with an enhanced strain element, has been used for more than a decade to model strain localization in materials including g...
Finite elements method (FEM) simulation based prediction of deformation and temperature at rolling of tubes on a pilgrim mill
FEM temperature tube rolling
2009/10/23
3D - FEM simulation was used as an efficient tool for description of stress-deformation thermal field at rolling of tubes on a pilgrim mill. The monitored objectives comprised also behaviour of workin...
