Structural Simulation: Buckling, Postbuckling and Collapse Analysis
Buckling and postbuckling behavior is critical to the success of certain designs. For example, crashworthiness of an automobile requires that particular vehicle components collapse in ways that maximize energy absorption. On the other hand, successful designs of imperfection-sensitive, thin-walled shell structures, ranging from beverage containers to large pressure vessels, must prevent unintentional buckling.
