摘要: The free vibration of laminated composite stiffened cylindrical shell panels in the presence cutout is investigated. A finite element code developed using eight-noded curved quadratic isoparametric for with a three noded beam stiffener and formulation validated through solution benchmark problems which were earlier solved by other researchers. Parametric study carried out varying size cutouts their positions respect to centre different edge constraints. results are presented form figures tables. further analyzed suggest guidelines select optimum position considering practical
