THEORETICAL BENDING COMPUTATIONAL ANALYSIS OFSANDWICH BEAM UNDER EXTERNAL LOADS

Abstract

Abstract: Using the geometric equations of shear strain and displacement of elastomer, the bending differential equations of sandwich beam are derived, and the bending deflection calculation of sandwich beam is studied. The bending deflection of sandwich beam under external load can be calculated by using the bending differential equation. However, the bending calculation of sandwich beams under external load in elastic theory has a disadvantage that only obtaining one problem in one solution. The method proposed in this paper overcomes this defects of the elasticity theory. The experimental results show that the proposed method in this paper has higher computational accuracy.

Key words: external load, sandwich beam, bending, calculation, deflection, test, composites
