MECHANICAL ANALYSIS OF REINFORCED PLATE STRUCTURES

Abstract: The paper presents the development of a new plate/shell stiffener element and the subsequent application in determine buckling loads and modes of different stiffened panels. The formulation of the stiffener is based on a general beam theory, which includes the constraint torsional warping effect and the second order terms of finite rotations. As part of the validation of the method, complete shell finite element analyses were made for stiffened plates
