In this work, an immersed boundary finite element method is proposed which is based on a hierarchically refined cartesian b-spline grid and employs the non-symmetric and penalty-free version of Nitsche’s method to enforce the boundary conditions. The... Read More about A stabilised immersed boundary method on hierarchical b-spline grids.

Subdivision based mixed methods for isogeometric analysis of linear and nonlinear nearly incompressible materials (2016)
Journal Article

This paper addresses the use of isogeometric analysis to solve solid mechanics problems involving nearly incompressible materials. The present work is focused on extension of two-field mixed variational formulations in both small and large strains to...
