| Abstract: | The mixed time integration parallel algorithm for
structural nonlinear dynamic analysis is proposed, which combines the
implicit and explicit time integration techniques. The parallel algorithm
with mixed time integration technique is implemented with domain
decomposition. Concurrency is introduced into this algorithm by integrating
interface nodes with the explicit time integration technique and solving local
subdomains with an implicit algorithm. A flexible parallel data structure is
designed to implement the parallel mixed time integration algorithm. A
computer program is developed with messaging interface
as the software development environment. Numerical example is implemented to
validate the performance of the parallel algorithm. It is shown
that the proposed algorithm is better in performance than the
implicit algorithm. |
