摘      要：On the basis about studying free bending for box beam with rectangular cross_section filled by honeycomb core,supplementary displacements and stresses of restrained bending for such beam were *** hypothesis for separated variables was adopted to solve *** to this,three aspect equations of geometrical,physical and balance were *** Galerkin s method,it is summed up as two_order ordinary differential equations with the attenuation *** makes clear that attenuation speed of stress is concerned with a big load or a small one,geometric dimensions of cross_section of beam,and physical parameter of material.
