In the present paper, on the basis of Reissner type modified assumption, a refined theory which considers the transverse shear effect on the transversely isotropic circular cylinders is established and a tenth order governing differential equation ia derived. This equation can be resolved into two parts, one second order partial differential equation and a pair of complex conjugate fourth order partial differential equations. In view of mechanics, the first part represents the effect of transverse shear and the second part represents the result of classical thin shell theory. If we let the transverse shear stiffness approach to infinity, the governing equation of refined theory can be reduced to the classical thin shell equation. Dropping some small terms, the Morley, Novozhilov and Donnell eguations can be derived from the two complex conjugate fourth order equations.

This paper presents two calculation methods for determining transverse shear stiffness coefficients: weight function method and strain energy me-thod. The first method is similar to that proposed in Ref.[1], with the exception of abandoning the assumption of parabolic distribution of trans-verse shear stress through thickness of the laminate.ate. Bccaus the real dis-tribution of shear stress is not exactly parabolic, especially for unsymm tr-ical laminates, the formula in Ref.[1] of ten yields inaccuracy.First of all, the formulas of transverse shsar stress were derived. The least square method was used to obtain the approximate weight functions for both symmetrical and unsymmetrical laminates. Then, the shear stiff-ness coefficients were calculated by using the two methods.The results show that for the unsymmetrical laminate the weight func-tion method is better than the formula of Ref.[l]. As for the comparison between the two methods of this paper, strain energy method might be sup-erior to the other one.

本文研究了十字叠层板横向剪切刚度系数的计算方法。指出前人采用的横向剪应力为抛物线分布的假设不够准确,使C_(ii)的计算值产生误差。本文首先推导了横向剪应力沿厚度分布的计算公式,然后用幂级数拟合了近似权函数,用权函数法和能量法对两种铺层结构的碳/环氧十字叠层板的C_(ii)进行了计算。对比了两种方法的结果,并与文献[1]的方法作了对比。结果表明,对于对称层板本文权函数法与文献[1]的结果基本一致;而对于非对称叠层板,二者差别明显。能量法结果与权函数法对比,前者更精确。
