Abstract

The paper proposes a topology optimisation methodology based on optimality criteria to solve structural and thermal problems. The results of its application to the optimal design of the brackets linking the Meteor & Debris Protection System panels to the main structure of the ISS module Columbus are shown. Keywords: topology optimisation, optimality criteria, Von Mises stress, heat flux. 1 Introduction The description of many physical problems leads to partial differential equations which have to be integrated under initial or boundary conditions [1]. In many cases it is possible to replace the problem of integrating a differential equation set by the equivalent problem of seeking a function which gives a minimum value to a variational functional. General rules for deriving natural variational principles from linear differential equ
