FEM-modelling of SSRT for Corrosion Tests

Abstract: This thesis discusses the mathematical formulation and computational treatment of slow strain rate corrosion tests based on nonlinear finite elements methods. The theory is illustrated by a description of classical small strain elastoplasticity theory as implemented in the Comsol Multiphysics 3.2 software package. The possible extension of the theory to finite strain is briefly addressed. Practical simulations and results regarding the evolution of stresses, strains and geometric deformation are also presented and discussed. Experimental data used in simulation where reported by Onchi, Takeo et al. and published in Journal of Nuclear Science and Technology in May 2006.
