摘要

The partial hybrid stress model proposed by Jing and Liao is combined with the higher order plate element to improve the through thickness distribution of deformations and stresses. Through dividing six stress components into flexural part (σx, σy, τxy, σz) and transverse shear part (τxz, τyz), the combination process can be proceeded by assuming hybrid stress for transverse shear while assuming higher order plate theory for flexural stresses in the Hellinger-Reissner principle. The resulting independent variables are displacements (u, v, w) and transverse shear (τxz, τyz) only. From the usual procedures of displacement element and hybrid stress element, this partial hybrid-higher order plate element can be established. The improvements of this new element in analyzing thick composite laminates are expressed through comparing with the results from elasticity and general higher order plate element. The convergence is also discussed.
