Abstract
Closed-form expressions are developed for the transverse shear and normal stresses in a rectangular anisotropic laminate under static bending. The procedure approximates the bending of a rectangular laminate by a combination of two mutually perpendicular cylindrical bending modes. In the proposed stress recovery scheme, the transverse shear stresses are related to the transverse shear stress resultants while the transverse normal stress is related to the applied pressure at the free surface. Results from selected examples show good agreement between the transverse stresses obtained from the present recovery scheme and the more rigorous plate theory solutions through the equilibrium equations of elasticity. The proposed recovery scheme is computationally efficient and can be implemented in finite element codes for analyzing composite structures.
