Detailed description of topics:

• Functional description
• General buckling phenomena
• Initial post-buckling behaviour
• Linear and nonlinear pre-buckling solution
• Buckling of discrete systems
• Buckling of finite element models
• Geometrical stiffness
• Geometrically nonlinear finite element analysis
• Eigenvalue analysis
• Sensitivity analysis

Course material:

Every student must prepare his own lecture notes. Some handouts will be provided. In addition, references to literature and textbooks will be given during the lectures.

References from literature:

Normal lectures will be provided. For further reading references to textbooks and literature will be given. Exercises will be distributed that lead to both analytical and numerical training. Several of these exercises require basic hands-on experience with finite element modeling.

Remarks assesment, entry requirements, etc.):

Assignments will be provided during the lectures. The answers must be handed in before the oral exam.

The final grade is based on the quality and completeness of the answers on take-home excersises and the quality of an oral exam.

Learning goals:

The course is designed to give the students a thorough foundation for solving the variety of structural stability problems they may encounter in practice.  Students become acquainted with both analytical and numerical techniques. The course is intended to place stability problems in a broad context. Therefore nonlinear buckling, post-buckling and design sensitivity analysis are also included.
