Mixed scheme of the finite-element method for the investigation of the interlayer contact problem in the refined formation. part 2: numerical analysis of contact stresses for bending of multilayer plates

摘要

Based on the discrete representation of plane layers in the framework of the {1,0}-approximation of the theory of thin plates, we propose an effective scheme of the finite-element method. A numeric analysis is made of the ideal interlayer contact in bi- and three-layer structures for various conditions of hinge support of plate edges in the case of plate bending by external pressure. We observe the effects of normal contact stress concentration in the plate edges and their dependence on the structural anisotropy in the transverse direction.
