Abstract

THE POST-BUCKLING BEHAVIOR OF COMPOSITE SHIPS’ STIFFENED PLATE PANELS HAS BEEN STUDIED. IN THIS STUDY, THE AVERAGE STRAIN- AVERAGE STRESS CURVES FOR THESE PANELS ARE DERIVED USING PROGRESSIVE FAILURE METHOD AS WELL AS NONLINEAR FINITE ELEMENT METHOD. THE BOUNDARY CONDITIONS ARE APPROPRIATE FOR THE CONTINUOUS PLATE PANELS USED IN SHIPBUILDING. THE EFFECTS OF THE ASPECT RATIO, INITIAL GEOMETRICAL IMPERFECTION AND STIFFENER SIZE ON THE POSTBUCKLING OF THESE STIFFENED PANELS ARE EVALUATED.
