Shape Optimization Of Two-dimensional Elastic
Body By Trefftz Method

Eisuke Kita, Takashi Yamamoto & Norio Kamiya
Abstract
This paper describes the shape optimization scheme of the two-dimensional
elastic structures using TVefftz method. In the Trefftz method, physical
quantities such as the stress, the strain and the displacement components are
approximated by the superposition of the related T-complete functions with
unknown parameters. Since the T-complete functions are regular, direct
differentiation of the quantities with respect to the design variables leads
to the design sensitivities. Sequential linear programming scheme using
the sensitivity analysis scheme is applied to the shape optimization of the
two-dimensional structures.
1 Introduction
Shape optimization problem of the structures is solved by using the finite
or boundary element method.
