Superior Time Step for Large Deformation Analysis by Dynamic Relaxation Method

In this paper a new time step will be formulated for Dynamic Relaxation method. For this purpose, residual force is minimized in each iteration. Calculation of the convergence rate shows the advantage of the recommended technique. For illustrating usability of this method, some plane and space trusses have been analyzed. In this paper, geometrical non-linearity is considered. Moreover, proposed method is widely examined by authorʹs computer program and some examples will be given.
