Aim: To provide a thorough understanding of structural stability with emphasis of influence of geometric imperfections. To provide computational tools for determination of carrying capacity of imperfect structures.
|
Contents: Necessary continuum mechanics foundation: Concepts of stability and instability with little emphasis on mathematics.
Elastic buckling: This part centers on asymptotic methods and their application to various structural examples that display several important features:
Plastic buckling and imperfection sensivity: Different examples, which elucidate important phenomena, are discussed:
Dynamic instability: Some theory and one example:
- Beck's column (follower forces)
Numerical Methods: The general equations are interpreted in terms of Finite Element Methods. Certain special, numerical problems are discussed, and various solutions are presented.
