Journal ArticleDOI
A framework for residual-based stabilization of incompressible finite elasticity: Stabilized formulations and F¯ methods for linear triangles and tetrahedra
Arif Masud,Timothy J. Truster +1 more
TL;DR: In this article, a new variational multiscale framework for finite strain incompressible elasticity is presented, which includes the classical F ¯ method as a particular subclass, and an error estimation procedure for nonlinear elasticity that emanates naturally from within the present multi-scale framework.
Journal ArticleDOI
A Discontinuous/continuous Galerkin method for modeling of interphase damage in fibrous composite systems
Timothy J. Truster,Arif Masud +1 more
TL;DR: A Discontinuous Galerkin (DG) interface treatment embedded in a ContinuousGalerkin formulation is presented for simulating the progressive debonding of bi-material interfaces, resulting in a pure displacement method amenable to traditional symmetric positive-definite solvers.
Journal ArticleDOI
Primal interface formulation for coupling multiple PDEs: A consistent derivation via the Variational Multiscale method
Timothy J. Truster,Arif Masud +1 more
TL;DR: In this article, a primal interface formulation is derived from a Lagrange multiplier method to provide a consistent framework to couple different partial differential equations (PDE) as well as to tie together nonconforming meshes.
Journal ArticleDOI
A variational multiscale a posteriori error estimation method for mixed form of nearly incompressible elasticity
TL;DR: In this article, an error estimation framework for a mixed displacement-pressure finite element method for nearly incompressible elasticity is presented, where the displacement field is decomposed into coarse scales that can be resolved by a given finite element mesh and fine scales that are beyond the resolution capacity of the mesh.
Journal ArticleDOI
A unified formulation for interface coupling and frictional contact modeling with embedded error estimation
TL;DR: In this paper, a variational multiscale method was proposed for the pure-displacement form and mixed form of small deformation elasticity as applied to the solution of two problem classes: domain decomposition and contact mechanics with friction.
