Abstract
This paper outlines the downfalls of using the finite element mesh to locate stress constraints for use in structural shape optimisation (SSO). A new method to specify the location of stress constraints is provided which is independent of the mesh. A surface point mapping procedure is implemented using a NURBS (Non Uniform Rational B-Spline) reparameterisation scheme enabling the provision of meaningful stress constraints to be supplied to the first order optimisation algorithm. A number of examples are provided to demonstrate the effectiveness of this SSO methodology.
