Investigation of the flexural stiffness of asymmetric multilayer beams

Abstract

We present the results of investigation of flexible stiffness of multilayer beams with geometric and/or stiffness asymmetry. An algorithm is proposed for the evaluation of coordinates of the geometric and stiffness centers and the analysis of flexural stiffness in any direction and its extreme values in multilayer beams with asymmetry of any kind. We study the kinetics of coordinates of the geometric and stiffness centers and flexural stiffness depending on the behavior of the geometric parameters and the ratio of the moduli of elasticity of layers and the cross-sectional shape of a multilayer beam.
