Linking Thermal Results as Input to a Thermal-Stress Simulation in Ansys Workbench — Lesson 6

In many engineering applications, a mechanical assembly may undergo significant temperature changes. Such temperature changes produce thermal strains and, under certain conditions, may also generate stresses. A thermal-stress analysis is necessary to evaluate the amount of warpage caused due to thermal strains and to prevent failure due to excessive stresses due to thermal conditions. To evaluate the thermal strains and stresses, we may first need to perform a thermal analysis to obtain the temperature distribution over the mechanical assembly. In this lesson, we will learn how to import the temperature results from a thermal analysis into a structural analysis in Ansys Workbench to calculate the strains, stresses and other results due to thermal loads. // INTERESTED IN MORE?
