Analytical solutions to predict flexural behavior of curved sandwich beams

Analytical solutions to predict flexural behavior of curved sandwich beams
Analytical solutions to predict flexural behavior of curved sandwich beams
This paper is concerned with the analysis of curved sandwich beams with a focus on debonding and buckling/wrinkling of the faces. An elasticity-theory-based approach is used for studying through-thickness tension in curved sandwich beam in the first section. The approach ensures an accurate description of the through-thickness stresses in curved sandwich beam. In the second section, the critical load for instability of a curved beam on an elastic foundation which is correspondent to the skin of sandwich beam, is considered and compared with the result for a flat beam on an elastic foundation. The flexural strength of sandwich beam is then studied with a view to identify debonding and local instability characteristics. The effects of various parameters, such as geometrical configuration, stiffness of the skin and core, on through-thickness tension stress and local instability respectively are also studied.

Abstract

This paper is concerned with the analysis of curved sandwich beams with a focus on debonding and buckling/wrinkling of the faces. An elasticity-theory-based approach is used for studying through-thickness tension in curved sandwich beam in the first section. The approach ensures an accurate description of the through-thickness stresses in curved sandwich beam. In the second section, the critical load for instability of a curved beam on an elastic foundation which is correspondent to the skin of sandwich beam, is considered and compared with the result for a flat beam on an elastic foundation. The flexural strength of sandwich beam is then studied with a view to identify debonding and local instability characteristics. The effects of various parameters, such as geometrical configuration, stiffness of the skin and core, on through-thickness tension stress and local instability respectively are also studied.
