Numberical Modeling of Axisymmetrical Thermoviscoplastic State of the Solids of Revolution Under Localized Thermal Effect

摘要

numerical approach for investigation of axisimmetrical thermoviscoplastic state of solids under variable thermomechanical lading is developed on the base of finite-element method. Mechanical response of material is governed with Bodner-Partom model. The problem of residual stresses In circular disc excited by shottime acting heat source localized in it's cener is considered. Experimental And numerical results are companied.
