Abstract

Based on the constitutive equation and deformation equation, the total stiffness matrix of laminated composite beam with T-section are built up by using the relation of 3D stress-stain transformation. Then calculation methods of the axial and bending stiffness of laminated composite beam with T-section are derived. Axial and bending stiffness of laminated composite beam with T-section are calculated under the uniformly distributed load or concentrated force with various boundary condition. A comparison between analytical calculation results and ANSYS calculation results shows good agreement. The results show that this method is reliable. And easy to apply in the initial design of composite hull. The research makes foundation for theoretically calculate laminated composite beam with arbitrary cross-section.
