BUCKLING FINITE ELEMENT ANALYSIS AND OPTIMIZATION IN GENESIS

This paper describes the implementation of bifurcation buckling finite element analysis and optimization in the commercial program GENESIS. For optimization, approximation concepts are used to reduce the number of full system analyses. The buckling responses are fully integrated so that in the optimization problem they can be combined with other existing analysis responses resulting from statics, dynamics and/or heat transfer. In addition, these responses can be combined with existing geometric and/or user responses. Example problems using buckling responses are described.
