Static Behavior of Anti-symmetric Angle-ply Composite Stiffened Cylindrical Shell with CutoutPages 163-185
Abstract:
The present work examines the static behavior of a laminated anti-symmetric angle-ply stiffened cylindrical shell in presence of cutout. The first-order shear deformation theory is used to model the stiffeners as well as the shell panel. The stiffeners and the shell panel surface are modeled using three-noded beam elements and eight-noded curved quadratic isoparametric elements respectively. Fiber orientation angle, layer numbers and six distinct boundary conditions are considered as the variables for the current study. The dimensionless values of displacement under static condition and stress resultants are calculated. The relative performance analysis of each shell combination is ranked based on their displacement and stress resultants. Several additional issues related to anti-symmetric angle-ply laminated stiffened composite cylindrical shells are also addressed.
