Possibility of identification of elastic properties in laminate beams with cross-ply laminae stacking sequences

Popis výsledku v původním jazyce

The goal of this work is to show the possibility of the identification of elastic properties in laminate beam specimen with cross-ply laminae stacking sequences using prescribed eigenfrequencies. These frequencies are not determined experimentally for the identification of laminate properties in this paper but they are calculated numerically with the help of the finite element software MSC.MARC. The composite material properties of a finite element model based on the Euler-Bernoulli theory have been subsequently tuned to correlate the determinate frequencies in cross-ply laminate beams with the natural frequencies established by the software package. A real-coded genetic algorithm and a uniform-micro genetic algorithm are applied as the inverse technique for the identification problem.
