Obtaining an Optimum Weight for a Composite Pressure Vessel
Weight of a composite cylindrical pressure vessel is an important issue investigated here. Design variables include number of layers and thickness, ply angle, volume fraction, and material properties in each layer. The constraint is based on Hoffman criterion and the optimization technique is a messy genetic algorithm (mGA). It is shown that with multilayered structure, we can have a vessel with a weight less than half of that for a single layered composite vessel under a given internal pressure.
