The Effects of Interlaminar Shear on the Bending and Buckling of Fiber-Reinforced,Composite,Flat and Curved Plates.

摘要

A small deflection plate theory is developed which includes higher order approximations to the effects of transverse shear. The governing equations and associated boundary conditions are developed by a variational method. The theory is sufficiently general to encompass anisotropic,laminated,composite,circularly curved,cylindrical plate elements of nonsymmetric cross section. Specific applications are made to the bending and the axial compression buckling of simply supported flat plates and to the axial compression buckling of curved plates and shells having classical,simple supports. It is shown that the effects of interlaminar shear can be significant in composite constructions which use very high strength fiber reinforcement. (Author)
