Stiffened aluminium panels subjected to axial compression

摘要

This paper presents axial compression tests on longitudinally stiffened aluminium panels in alloy AA6082 temper T6. A specially designed test facility is presented. The panels are built up with extruded aluminium profiles connected by longitudinal welds. Two panel types are considered, with open section (L-shaped) stiffeners and closed section stiffeners, respectively. The experimental programme comproises tests on single panels supported along all four edges And as a special case panels supported at two edges only.
