Abstract : A previously derived model of ratedependent plasticity is modified for use in a finite element stress analysis code. The code allows nearly axisymmetric bodies to be analyzed by a perturbation of the symmetric solution. It contains anisotropic yield conditions. The formulation of rate effect is added to the code and a test problem of a uniaxial tensile experiment is solved. Convergence to the exact solution is shown. (Author)
