Residual Strength Assessments of Defective Stiffened Plates Used in Marine and Aerospace Structures

Author(s): Osama Bedair.


The paper reviews recent research work developed for the analysis and design of defective stiffened panels with application to marine and aerospace structures. The review is limited to recent research work evolved over the past three decades. Varieties of numerical modeling philosophies and experimental techniques are discussed. The paper addresses various types of damages such as residual stress, fatigue cracks, manufacturing imperfections, corrosion and welding distortions. The paper also reviews recent patents developed using stiffened plates.

Keywords: Stiffened plates, residual stress, fatigue cracks, imperfections, corrosion, composite panels, manufacturing defects, Aerospace Structures, optimization techniques, thin walled panels, stiffening element, Bridge girder, stiffened plate panels, multiple-stiffener plate structures, stiffened ductile panels
