Sparse algorithms for indefinite system of linear equations
Sparse LDLT algorithms, based upon mixed forward-backward factorization strategies, are developed for direct solution of indefinite system of linear equations. A simple rotation matrix is also introduced and inc...

Parallel Non-linear Analysis of Laminated Rubber Structures
General purpose finite element codes have been widely used for both linear and non-linear structural problems. Many of the real-world problems in structural applications are large in size, and require extensiv...

Nonlinear Deformation Responses of Rubber Components by Finite Element Analysis
Typically, rubber under the influence of mechanical loads exhibits strong nonlinear behavior due to both material and geometrical nonlinearities. Structural analysis of such material via finite element method ...

Large strain analysis of rubber-like materials based on a perturbed Lagrangian variational principle
A mixed finite element method is presented for the large strain analysis of rubber-like materials, which are considered to be nearly incompressible. Two types of constitutive relations are included: generalize...
