Abstract

This paper presents an analytical solution for static analysis of moderately thick laminated composite wide beams whose fiber orientation angle varies continuously through the thickness direction. Since these anisotropic beams have such a monoclinic stiffness matrix form, the strain components which are ignored for isotropic wide beams must be taken into account. To this end, a refined displacement field taking into account the entire shear strains is used. The equilibrium equations are obtained and solved analytically for beams with different boundary conditions. Stress and displacement components of the functionally graded (FG) beam are obtained, and the effects of FG parameter, boundary condition and length–thickness ratio are studied.
