FREQUENCY CHARACTERISTICS OF ELASTICALLY FASTENED CANTILEVERED LAMINATED BEAMS

摘要

We consider the application of a new method aimed at the analysis of the stress state to the evaluation of the influence of the conditions of fastening of laminated beams on their dynamic properties. We study the stress state in the zone of fastening in detail. The proposed theoretical model includes the analysis of strains in layers with regard for the transverse shear strains and normal strains and stresses. We carry out the numerical analysis of the dependence of the frequency spectrum on the anisotropy of the mechanical properties and stress distribution in the region of elastic fastening.
