What is Simulation of Hydrogen Embrittlement in Zirconium Alloys Under Stress and Temperature Gradients about?
A ®nite element model is presented for hydrogen embrittlement of zirconium alloys. The model takes into account the coupled processes of hydrogen diusion, non-mechanical energy ̄ow, hydride precipitation, hydride/solid solution deformation and fracture.The model has been tested successfully against the Sawatzky experiment and exact analytical solutions on hydrogen diusion and hydride precipitation under a temperature gradient. Based on this model, the hydrogen embrittlement of a Zircaloy-2 cracked plate, is studied under tensile stress and temperature gradient. The initial and boundary conditions are according to those encountered in the fuel cladding of light water reactors during operation. The strong eect of crack tip stress intensi®cation on hydrogen diusion and initial hydride precipitation is shown. The problem is also studied by considering near-tip material damage which aects hydride precipitation signi®cantly.
