摘要
The stress, deflection, and neutral-surface behaviour is investigated for cylindrical bending and rectangular plate bending of thick laminates of composite materials having soft transverse shear moduli and different elastic properties depending on whether the fibre-direction strains are tensile or compressive. The higher-order individual-layer laminate theory, previously developed by the present investigators, treats each layer separately using an independent higher-order displacement field. Numerical results for single-layer plates and laminates having all edges simply supported and subjected to sinusoidally distributed normal pressure are obtained and compared with results from Pagano's elasticity theory and other approximate plate theories. The predictions of the present theory show better agreement with the elasticity-theory results than any of the other approximate theories. © 1990.
