Two-dimensional shape optimal design by the finite element method |
|
| Authors: | J P Queau Ph Trompette |
| Abstract: | This paper is concerned with the optimal shape design of plane or axisymmetric structures in order to minimize the stress concentration factor along the boundary. This boundary is described by straight lines and circles. The structure is analysed using the finite element method, and the optimization procedure is based on an extended interior penalty function. Three example problems are reported. |
