On bifurcation sensitivities and stability optimization based on local sub-domain eigenvalues

Abstract eng:
The engineering approach of fully stressed design is a practical tool with a theoretical foundation. The analog approach to structural bifurcation instability optimization is presented with its theoretical foundation. A numerical redesign procedure is proposed and illustrated with examples. For the ideal case, an optimality criterion is fulfilled if the design have the same sub-domain ”critical load” (local Rayleigh quotient). Sensitivity analysis results in a simple relation between system critical load and local ”critical load” for a given bifurcation mode.
