Shape optimization of quasi-brittle axisymmetric shells by genetic algorithm
چکیده انگلیسی

This paper describes the application of genetic algorithm to the shape optimization of axisymmetric shells. The primary problem of axisymmetric shell optimization under fracture mechanics constraint is formulated as the weight (volume of shell material) minimization under stress intensity constraints. It is assumed that the shells are made from quasi-brittle materials and through-thickness crack presence is admitted. Taking into account the fact of incomplete information concerning crack arising (size, location and orientation) this paper presents some numerical results based on a guaranteed approach.
