Abstract

This paper deals with the thickness optimisation of layers of a bi-stratum composite structure having infinite lateral dimensions. The composite is considered as a one-dimensional structure. Using a direct integration of the behaviour equation an analytical solution can be obtained without expensive calculation time. This approach is based on the techniques which are applied to acoustic analysis of multi-layer structures and can be extended to calculate a general composite laminate structure. The advantage of such a method is a short calculation time. The objective of this paper is to minimise the Von Mises stress in average with respect to the position of the interface between two layers. The analytical solution is obtained in a similar way as for analysis prob
