Résumé :	Conventional optimization methods for composite structures often in-volve issues such as local minima, slow convergence (in some cases, no convergence at all), etc. A bigger issue is that the optimal solution often results in fibre discontinuity throughout the structures, which is not feasible from the manufacturing point of view. Here, we offer an alternative, yet simple approach to optimize composite structures subject to various loading conditions: the Profile Rank method.
Note de contenu :	- Material properties of C-Ply laminates with different layups and of various metals used in the profile rank study - Thickness profile along the beam span with various exponents of the cosine function ; beam weight against the power exponent - Weight vs. exponent ; thickness variation along beam span - Optimal thickness profile along beam length subject to concentrated and distributed loading conditions - Optimal thickness profiles along beam length subject to concentrated loading with various C-Ply layups and aluminium ; relative weight compared with aluminium - Relative weight of various metal beams compared with QI C-Ply composite laminates
