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.

Industrialization of any importance started in Hungary only in the closing decades of the last century. Capital came from abroad, in the first place from Austria. The country became independent after the First World War, yet economic conditions hindered the progress of industry. The best part of the national income still came from agriculture. During the Second World War German concerns gave some impetus to Hungarian
industry; the new plants, however, were constructed mostly on plans made abroad. As a matter of fact, Hungarian industrial architecture dates only from about fifteen years ago, though the country had attained a high level in the art of building.
