Abstract

The bending of threelayer elastic beam partial support pattern on the elastic basis with stepped variable thickness of one of two stiff shells is considered. To describe kinematics of asymmetrical over thickness core pack the hypotheses of the broken normal are accepted. A system of equilibrium equations in terms of displacements has been derived. Analytical deciding a problem are received and their numeric analysis are conducted.

Keywords
