Buckling Analysis with Thermal Expansion | Ansys Mechanical

Thermal growth can covertly drive structures into compressive stress and catastrophic buckling. In this session—recorded several years ago—our engineer shows step-by-step how to predict buckling triggered by thermal expansion inside Ansys Mechanical. You’ll see where linear-eigenvalue, nonlinear, and load-scaling approaches each shine, and how to extract the critical load factor with confidence. Key takeaways Importing temperature loads and mapping thermal strain to structural parts Setting up linear-eigenvalue, nonlinear, and stabilized post-buckling analyses Choosing contact & boundary conditions that keep results realistic Interpreting mode shapes to spot failure-prone regions early Learn more about Ansys Workbench Mechanical: https://simutechgroup.com/services/an...
