Abstract

An approach to optimizing variable stiffness laminates for strength is modified to allow for the optimization of curved structures. A density function to take in account the effect of gaps and overlaps during optimization created by fibre steering is found with the functional approximation method. The density plot of a plate for 2 standard cases is compared, after encountering complications an alternative solution is proposed with the finite element method.
