A dual Craig–Bampton method for dynamic substructuring

A dual iterative substructuring method with a penalty term

An iterative substructuring method with Lagrange multipliers is considered for the second order elliptic problem, which is a variant of the FETI-DP method. The standard FETI-DP formulation is associated with the saddle-point problem which is induced from the minimization problem with a constraint for imposing the continuity across the interface. Starting from the slightly changed saddle-point p...

On the convergence of a dual-primal substructuring method

Improved Dynamic Substructuring on

For solving the eigenvalue problem of a structural system having a large number of degrees of freedom the authors introduced in 6] the improved condensation method using the Rayleigh functional of the exactly condensed nonlinear eigenvalue problem. In this paper we discuss the implementation of the method for substructured problems on a distributed memory MIMD Computer. Examples are presented w...
