Abstract

Calculations in the final element program ANSYS complex showed that tension which arise in layered samples at loading do not depend on quantity of layers if the total thickness of materials with different values of the module of elasticity does not change. The model is developed for calculation of tension in each layer of a layered plate. The schedule of dependence of settlement factor for calculation of tension in a layered sample from the relation of modules of elasticity of its materials in case of equal thickness of layers with different values of the module of elasticity is constructed. The system of the equations, allowing to define tension in plate layers with different values of the module of elasticity is offered.
