Abstract

Deformation due to stress and strain that lead to an initiation of crack and then propagates is usually being modelled satisfactory by using finite element method (FEM). The mathematical model has developed by using the correlation between the forces applied to the individual elements and the nodal displacements. The element stiffness matrix which has been set up earlier can be used to illustrate the elastic deformation since the numerical FEM is emphasized as a platform for discretization of one-dimensional continua problems where the stress is uniaxial and implemented on parallel algorithm using the distributed parallel computer system. Parallel algorithm which based on parallel computing systems is used to capture the visualization of the overall extension and the stress distribution in a linearly tapered bar of circular section with an end load. The results obtained from the finite element approximation will be presented graphically in this paper. In this study, Parallel Virtual Machine (PVM) is used, which is a software tool for parallel networking of computers and also using C language based on Linux platforms. Moreover, it permits a network of heterogeneous machines to be used as a single distributed parallel processor. In this study, the performance measurements of algorithm from the aspect of speedup, effectiveness, efficiency and temporal performance are analysed.
