✦ Synopsis


Stress resultants and moments around the holes of infinite unsymmetrical composite laminates under remote uniform loading are analyzed using the complex potential approach developed by Chen and Shen [Mech. Res. Commun. 28 (4) (2001) 423; 28 (5) ( 2001) 513]. In the analysis, the authorsÕ previous work has been modified to determine the complex constants B k appeared in the complex potential functions of Chen and Shen [Mech. Res. Commun. 28 (5) ( 2001) 513]. Herein B k are the unknown quantities related to the remote loading conditions. The effect of bending extension coupling has been discussed for several laminates such as [0/90] T , [45/)45] T and [0/90/45/)45] nT . Results indicates that the coupling between bending and extension significantly affects the stresses around the hole of an unsymmetrical laminate containing one sub-laminate only. Such the effect rapidly decreases as the number of the sub-laminates increases. The results confirm the validity of the developed complex potential approach.
