How are nonlinear materials modeled in FEM?

Mixed finite element methods are a generalisation of staggered finite difference methods, and are in- tended to address the same problem: spurious pressure mode ... ... finite element method for MHD models on Lipschitz domains. Research output: Journal Publications and Reviews › RGC 21 - Publication in refereed journal. Integration of finite element analysis (FEA) into the vertex model achieved a better fit with the biological model. Therefore, the FEM model provides a basis ... Application of the finite element method in biomechanics. SS'93 High Performance Computing: New Horizons, June 6-9, 1993, Calgary, AB, Canada, Calgary, AB ... To solve a problem, FEM subdivides a large system into smaller, simpler parts called finite elements. This is achieved by a particular space discretization in ... Abstract. The extended finite element method allows one to model displacement discontinuities which do not conform to interelement surfaces. This method is ...
