Abstract
The orientation of fibre direction in layers and number of layers of composites
play a major role in determining the strength and stiffness. Thus the basic
design problem is to determine the optimum stacking sequence of the composite
laminate. Many methods are available at present for the design optimisation of
structural systems. However, these methods are based on mathematical
programming techniques involving gradient search and direct search. These
methods assume the variables are continuous. In this paper a different search
and optimisation algorithm, known as the Genetic algorithm of Goldberg [1],
has been successfully applied to obtain optimal fibre orientation of multi-layer
plates, which considers the angle of fibre orientation as a discrete variable. The
