Abstract

A kinked bar with two rectangular knees is shape optimized with respect to different single and one combined loading case. A guideline to shape optimization is given for combined loading. It was found that if the kinked bar is shape optimized with respect to the most unfavorable case of combined loading, the final optimum design will be also weight optimized. However if single load cases which are part of this combination or sub‐combinations are applied the design is still safe, but not weight‐minimized furthermore. The shape optimization was carried out with the CAO‐method (CAO: Computer Aided Optimization) which is based on a computer simulation of biological growth. It is a new method developed in the Karlsruhe Nuclear Research Center.

The natural frequencies and normal mode shapes become important in devices that are subject to vibration and in those that operate at high speeds in the dynamic regime. Some devices, especially at micro scale in micro-electro-mechanical systems (MEMS), are intentionally operated at resonance frequen
