The higher-order shear deformation theory has been applied in the analysis of laminated composite structure. In this paper, the zigzag model of composite laminated beams using the trigonometric function is presented. The lateral displacement and strain is assumed to the sin-function which embodies approximately layer-wise behaviors based in existing data. The higher terms are ignored in the transverse deformation and also, the shear strain and stress is supposed in the cos-function. Applying… 

The higher-order shear deformation theory has been applied in the analysis of laminated composite structure. In this paper, the zigzag model of composite laminated beams using the trigonometric function is presented. The lateral displacement and strain is assumed to the sin-function which embodies approximately layer-wise behaviors based in existing data. The higher terms are ignored in the transverse deformation and also, the shear strain and stress is supposed in the cos-function. Applying this model to composite laminated beams, the governing equations are induced and the boundary condition is assumed the simple support. According to symmetric or antisymmetric, the model having the various lenth-to-thickness ratio and layer of number is analyzed. The result in this paper is compared with the existing results for the accuracy of the model.
