摘要：The interlaminar stresses of a carbon fiber-reinforced laminated plate
   with a hole were analyzed using three-dimensional finite element
   numerical simulation. This laminated plate was subjected to uniaxial
   forces and composed of layers with typical ply angles ［0/45/-45/90］. The
   effects of the ply parameters on the interlaminar stress distribution
   were investigated; in the meantime, the maximum value and detailed
   distribution of interlaminar stresses in different typical interfaces
   were presented. The results show that the location of interfaces along
   thickness only affects the magnitudes of interlaminar stresses but not
   the trend of distribution, and the stacking sequence (［angle 1/angle 2］
   or ［angle 2/angle 1］) affects neither the magnitudes of interlaminar
   stresses nor the trend of distribution. Furthermore, the maximum normal
   stress of interface occurs between ［-45/90］ layers at 90° from the
   loading axis with its value reaching 51% of the value of applied stress,
   the maximum interlaminar shearing stress occurs between ［-45/0］ layers:
   the maximum circle shearing stress occurs at 74° with its value reaching
   64% of the value of applied stress, and the maximum radial shearing
   stress occurs at 66° with its value reaching 25% of the value of applied
   stress.
