Global multiscale optimization design of composite laminated frame structure

Abstract eng:
The concurrent multiscale optimization design of composite frames is investigated with gradient-based optimization algorithms. The winding angle in micro-material scale and the geometrical parameter of components of the frame in macro-structural scale are introduced as the independent variables on the two geometrical scales. The coupling effect of macro- and micro-scale design variables can be fully considered in the established multiscale optimization model to probe the potential of composite structures. The feasible domain is found to be non-convexity with the fiber winding angle as micro-material design variable. Then a new two-step optimization scheme is proposed to investigate the optimization design of the composite frame with minimum structural compliance, which increases the possibilities to find the global optimum with the gradient based algorithm.
