The paper deals with identification of material constans in fibre-reinforced laminates. The Evolutionary Algorithm is used as the global optimization method. The grandiet method supported by the Artificial Neutral Network is used as the local optimization method. Material constans are presented in the form of fuzzy numbers to model their uncertainty. Two types of laminates are considered: simple and hybrid ones. Modal analysis methods are used to collect data necessary for the identification process. The Finite Element Method in fuzzy version is used to solve the direct problem for the laminates. Numerical examples are attached.
