Abstract: | The paper explores the possibility of performing limited shape/size optimization to obtain a minimum weight design using rigid body movement. A two step approach is adopted where changes in the shape parameters are made separately from changes in the size parameters. The sizing step uses a conventional optimization, STARS, which is available commercially. For simplicity the method is demonstrated using planar arches subject to a variety of load and boundary conditions. |
