Abstract: This paper presents an approach to parameterization based shape optimization of statically loaded elastic structures. The shape parameterization is based on the design element technique and a rational Bezicr body is used to serve as the design element. Practical implementation issues related to the introduction of design variables are discussed briefly. The design sensitivity calculation is based on the discrete approach. The proposed solution process layout is based on a stand-alone optimization program which makes use of compatiblc analysis programs called simulators. For illustrationpurpose an example problem containing shape and sizing design variables is formulated and solved. The range of use of the proposed approachis illustrated with three further examples.Keywords: mechanics, structure parameterization, shape optimal design, finite element mesh, body parameterization, design element, Bezier bodyPublished in DKUM: 01.06.2012; Views: 2028; Downloads: 75 Link to full text
