DETERMINATION OF THE ELASTIC MODULI OF LAYERED BEAMS BASED ON THE RESULTS OF EXPERIMENTAL INVESTIGATIONS AND NUMERICAL MODELS

摘要

On the basis of the higher-order theory for layered anisotropic plates and experimentally measured deflections under the conditions of three-point bending of layered beams, we propose a method for the identification of their elastic moduli. The theoretical model takes into account the shear and normal strains and stresses. The moduli are found by minimizing the deviations of the computed values of deflections from the experimental data.
