Two approaches for parallel implementation of nonlinear transient dynamic analysis algorithms have been presented in this paper. One is based on geometric decomposition, and the other one is processor‐farm approach. Both shared memory (Magnum IV) and transputer‐based message‐passing systems have been chosen for implementation of the proposed parallel algorithms for dynamic analysis. Multithread concepts have been employed on transputer networks to optimize the code by overlapping communications with computations. Numerical studies indicate that explicit transient dynamic analysis can be implemented effectively employing geometric decomposition technique both on shared and message‐passing systems.
