Big Bang – Big Crunch Optimization Method in Optimum Design of Complex Composite Laminates

نویسنده

  • Pavel Y. Tabakov
چکیده

An accurate optimal design of laminated composite structures may present considerable difficulties due to the complexity and multi-modality of the functional design space. The Big Bang – Big Crunch (BB-BC) optimization method is a relatively new technique and has already proved to be a valuable tool for structural optimization. In the present study the exceptional efficiency of the method is demonstrated by an example of the lay-up optimization of multilayered anisotropic cylinders based on a three-dimensional elasticity solution. It is shown that, due to its simplicity and speed, the BB-BC is much more efficient for this class of problems when compared to the genetic algorithms. Keywords—Big Bang – Big Crunch method, optimization, composite laminates, pressure vessel.
