The study of the possibilities of residual stresses prediction in weld joint using the elastic-viscoplastic material model
Original language description
This contribution is a study how to analyze the stress-strain responses to technological processes which are applied to special high-alloy steel with polymorphic behaviour for the energy industry. These are technological processes of welding and post weld heat treatment (PWHT) analyzed experimentally and by computational modelling. Residual stresses always arise during welding and PWHT in the weld joint and its surrounding. One of the requirements for the quality of weld joints of machine components isan adherence to a certain level of residual stresses especially for components in energy industry. The possibility of correct and effective prediction of residual stresses in the weld joint is the subject of this contribution. At present it is possible to computationally modelling the processes of welding and PWHT. The elastic-plastic material models are standardly used for computational modelling of these tasks. These constitutive models are not able to describe significant viscoplastic
