Stresses near corners of skewed stiffened plates

Stresses in the proximity of obtuse and acute corners of skewed stiffened plates cannot be accurately predicted by analytical methods owing to the steep stress gradients and the complicated boundary conditions. An experimental study was carried out on 1/4 in. thick 30° and 45° aluminium skewed stiffened plates carrying concentrated load to determine the stresses near such corners. It was found that there were stress concentrations at the corners, these being more pronounced at the obtuse corners. Suggestions for adequate corner reinforcements are given. J. B. KENNEDY and I. C.
