Buckling, Postbuckling, and Collapse Analysis with Abaqus
Objective:
Buckling and postbuckling behavior is critical to the
success of certain designs. For example, crash worthiness
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.
This course blends the theoretical background on such
topics as geometric nonlinearity and the Riks method
together with examples, guidelines, and workshops to
demonstrate how to:
- Identify an imperfection-sensitive structure
- Extract closely spaced eigenvalues efficiently
- Introduce imperfections into a "perfect" mesh
- Use the Riks method effectively
- Use damping to control unstable motions
Who should attend:
This course is recommended for engineers with
experience using Abaqus/Standard.
