Rectangular Plates with Stiffeners: The Buckling of Simply Supported Plates under Compressive Stress

The Differential Equation of the Problem and the Solution. A RECTANGULAR plate of length a with simply supported edges is reinforced by equal longitudinal ribs at equal distances b and is submitted to the action of uniformly distributed compressive forces N along the x‐axis (Fig. 1). For every strip b we have the differential equation for the deflection w
