A Galerkin least-square stabilisation technique for hyperelastic biphasic soft tissue
Julien Vignollet, Chris J. Pearce, Lukasz Kaczmarczyk
An hyperelastic biphasic model is presented. For slow-draining problems (permeability less than 1\times10-2 mm4 N-1 s-1), numerical instabilities in the form of non-physical oscill…
Corotational formulation for 3d solids. An analysis of geometrically nonlinear foam deformation
Łukasz Kaczmarczyk, Tomasz Koziara, Chris J. Pearce
This paper presents theory for the Lagrange co-rotational (CR) formulation of finite elements in the geometrically nonlinear analysis of 3D structures. In this paper strains are as…
A micromechanics-enhanced finite element formulation for modelling heterogeneous materials
J. Novák, Ł. Kaczmarczyk, P. Grassl +2
In the analysis of composite materials with heterogeneous microstructures, full resolution of the heterogeneities using classical numerical approaches can be computationally prohib…
