| Abstract: | This paper presents a study on the failure load and deformation of CFRP box beams based on the fracture of individual laminas. Two different CFRP laminate structures are tested and analyzed: quasi isotropic (QI) and cross ply (CP) laminate. Nonlinear constitutive law is obtained by considering the fracture of individual laminas, and the law is implemented into a fiber model to obtain the failure load of the beams. The fiber model is also used to obtain the flexural deformation of the beams, while Timoshenko beam is referred to obtain the shear deformation. Analysis shows a good agreement on the failure load and load-displacement relation of the two kinds of beams which show a different flexural response. |
