Application of Bezier curves for description of structure shape in optimization of adhesive joints

The problem of topological optimization a symmetrical double-shear adhesive joint has been solved. suggested mathematical model with variable thickness generalizes the classic Holland–Reissner model. shape doubler is described by means Bezier curve. Seeking parameters in are coordinates reference points Both length and cross-section area can be considered an objective function. restriction applied on stress film doubler. direct finding state at given geometric was solved using finite difference method. genetic algorithm used to solve problem. In order improve convergence algorithm, island evolution suggested, which ensures quick selection stability obtained results.
