Evolutionary identification of laminates? granular parameters. (Received in the final form November 12, 2010)

Journal Title: Computer Assisted Methods in Engineering and Science - Year 2010, Vol 17, Issue 1

Abstract

The paper deals with the identification of material constants in simple and hybrid laminates. It is assumed that identified constants are non-deterministic and can be described by means of different forms of the information granularity represented by interval numbers, fuzzy numbers or random variables. The Two- Stage Granular Strategy combining global (Evolutionary Algorithm) and local (gradient method supported by an Artificial Neural Network) optimization techniques is used to solve the identification problems. Finite Element Method in the granular form is used to solve the direct problem for laminates. Modal analysis methods are employed to collect measurement data
