Abstract
A simple Self-Designing Structure's [SDS] based procedure
to add and remove material simultaneously along a boundary
is developed to optimize the shape of two-dimensional elastic
problems and to minimize the maximum von Mises stress.
The SDS results for the two dimensional infinite plate with a
hole, are very close to the theoretical results of an elliptical
boundary. For the fillet problem the SDS program reduces
the stress concentration to a half. The proposed shape
optimisation method, when compared with existing
derivative based shape optimisation methods has many
features such as simplicity, applicability, flexibility,
computational efficiency and a better control of the stresses
on the design boundary.
