Abstract

Industrial applications of shape and topology optimisation and new approaches for shape optimisation considering fatigue E. Schnack*, R. Meske^, J. Sauted and W. Weikl* ^ Institute of Solid Mechanics, Karlsruhe University, Germany ^ FE-Design GmbH, D-76131 Karlsruhe, Germany Abstract The pioneering works of Schnack et al. [1,2] were taken up by Sauter in 1991 with the aim to apply the gradientless structural optimisation to large real-world engineering problems. This led to the development of the computer program CAOSS. The principle of structural optimisation based upon optimality criteria was successfully extended from shape optimisation to topology optimisation [3]. In the presentation, a short introduction and survey on structural optimisation will be given. Moreover, several industrial applications of topology and shape optimisation with CAOSS will be shown. First, an example on shape optimisa- tion of a hyperelastic material structure is shown, where multiple non-linearities occu
