Computational framework for monolithic coupling for thin fluid flow in contact interfaces
Andrei G. Shvarts, Julien Vignollet, Vladislav A. Yastrebov
We developed a computational framework for simulating thin fluid flow in narrow interfaces between contacting solids, which is relevant for a range of engineering, biological and g…
Stabilized MorteX method for mesh tying along embedded interfaces
Basava Raju Akula, Julien Vignollet, Vladislav A. Yastrebov
We present a unified framework to tie overlapping meshes in solid mechanics applications. This framework is a combination of the X-FEM method and the mortar method, which uses Lagr…
MorteX method for contact along real and embedded surfaces: coupling X-FEM with the Mortar method
Basava Raju Akula, Julien Vignollet, Vladislav A. Yastrebov
A method to treat frictional contact problems along embedded surfaces in the finite element framework is developed. Arbitrarily shaped embedded surfaces, cutting through finite ele…
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…
