ABSTRACT
ABSTRACT: In this work the Plastic Domain Decomposition (PDD) Method is implemented for parallel elastic-plastic finite element computations related to Soil-Foundation-Structure Interaction (SFSI) problems. The PDD provides for efficient parallel elastic-plastic finite element computations steered by an adaptable, run-time repartitioning of the finite element domain. The adaptable repartitioning aims at balancing computational load among processing nodes (CPUs), while minimizing inter-processor communications and data redistribution during elasto-plastic computations. The PDD method is applied to large scale SFSI problem. Presented examples show scalability and performance of the PDD computations. A set of illustrative example is used to show efficiency of PDD computations and also to emphasize the importance of coupling of the dynamic characteristics of earthquake, soil and structural (ESS) on overall performance of the SFS system. The aformentioned ESS coupling can only be investigated using detailed models, which dictates the use of parallel simulations.
