Abstract
A nonlinear finite element formulation for beams and arches is presented for implementation on a multiple instruction multiple data (MIMD) parallel machine. A twelve degree of freedom arch element is developed using Green strains and 2nd Piola Kirchhoff stresses. Concepts like loop splitting and expression splitting are used to improve the load balancing capability among the processors. Using this developed element, beams and arches that are undergoing large displacements and large rotations are analyzed, and efficiency of the program is compared with a sequential implementation.
