Deflection Computations of the Double Composite Cantilever Beam

Abstract:

Considering of the hypothesis of small deformation, the deflection approximate differential equation of beam and integration equation theory and numerical methods are used to the deflection problems of the double composite cantilever beam. The deflection problem of the double composite beam with smooth interface under a point vertical force acting on the beam end are analyzed concretely, the analytical solutions of the touching distributing force and the cross section rotation angle function are given, and the concrete method of computing the beam deflection is put forward based on the Gauss-Legendre integration formula, the results of the given example show the validity. The methods and the conclusions here can be extended to study the deflection problems of composite cantilever beam with arbitrary layers and the deflection problems of composite beams with other supporting condition, they are important to the designs of the engineering beams.
