Abstract

Aluminum alloys are now acknowledged as successful materials in building ships and boats with high-speed capability and long-life cycles as well as in the production of components for offshore platforms, because of their distinguished mechanical properties. Lighter weight, high corrosion resistance, and inexpensive maintenance are all advantages of aluminum compared to steel. The structural longevity of aluminum alloys is somewhat like that of steel when affected by cracking damage. The evaluation of the effect of cracks on the ultimate strength and collapse behavior of various ship structural members, is essential to avoid complete structural failure; it would also serve the life-cycle management, maintenance, and repair strategies. The abundant existing literature dealing with the residual strength of aluminum stiffened and unstiffened panels does not include studies concerned with the behavior of cracked aluminum panels. This study aims to investigate experimentally and numerically the residual capacity of aluminum stiffened panels with locked cracks and the buckling behavior of the cracked panels under uni-axial compressive load. The application of the study to assess the effect of locked crack length, location, and orientation on the collapse behavior of aluminum stiffened panels is intended to fill the existing research gap and provide data similar to the abundant published data for stiffened steel panels with locked cracks. A full-scale experimental compressive test of an intact stiffened aluminum panel made of AA5083-H116 like an existing panel used in marine applications, has been performed to acquire complete experimental data regarding its collapse behavior and load-carrying capacity.
