Abstract
Some present requirements of the mechanical structures are high strength and lightweight. A solution is to adopt the hollow structure design. In mechanical engineering industry are commonly using hollow structural sections, surface – type and even three dimensional hollow parts. The final shape is usually the result of structural optimization in which smallest material quantity fulfil the strength requirements. In this paper the study considers a different distribution of the same mass, more exactly starting with a single whole and “splitting” its surface in smaller and smaller holes each iteration. The intuitive expected result in reducing equivalent stresses considering von Mises criteria was not achieved.
