Abstract
The main objective of the proposed research is to develop parallel nonlinear finite element methods and implementation for three-dimensional dynamic elasto-plastic analysis that can be used to simulate nonlinear earthquake response in large basins. The tasks required for achieving the goal of the proposed research are presented. The main tasks are to choose an appropriate soil plasticity model and incorporate it into the finite element computational process, to design efficient, accurate, and economical numerical methods for solving elasto-plastic problems with a large number of degrees of freedom on parallel computers, and to illustrate the developed methodology by examining in detail the seismic response of an idealized three-dimensional basin.
