Abstract

The CAO method (Computer Aided Optimisation) was developed at the Forschungszentrum Karlsruhe as a shape-optimisation-program for the simu- lation of natural growth processes of biological load carriers. With the help of CAO it is on principle possible to optimise any loaded engineering component. After the optimisation with CAO this component shows a constant stress distribution on its surface. Because of that, the existing material will be used optimal by simultaneous low weight. Up to ABAQUS Version 5.3 it was only possible to use shell or membrane elements with a constant wall thickness by the application of the FEM- Software ABAQUS. With the release of ABAQUS Version 5.4 a modification of CAO now allows a variation of the wall thickness
