THE STRESS-STRAIN STATE OF LAYERED COMPOSITE RODS AND BLADES UNDER TORSION

Cover Page

Abstract


In the paper, the technique of the solution of a problem on torsion of layered anisotropic rods by a method of final elements (FEM) is presented. A problem on torsion of rods of rhom- bus cross section of compress blade is considered. In the paper, the algorithm is discovered with the help of FEM, giving the opportunity to calculate displacements, deformations and stresses, and torsion rigidity of multilayered rods of arbitrary section under torsion too. The values of axial displacements of rhombus cross section calculated with the help of FEM are compared with their exact values.
