摘要：
The local subdomain formulation (LSF) for nonlinear dynamic analysis of large-scale structures is presented using domain decomposition and preconditioned conjugate gradient (PCG) technique. The formulation operates on the local unassembled subdomain matrices and the preconditioner is constructed using the local subdomain information. Newmark-beta average acceleration technique is employed for time integration. Numerical results indicate that the proposed LSF formulation is superior in performance when compared to the conventional domain decomposition algorithms.
