Rigidity of Circular Plates with Radial Ribs, Placed on One Side, Neglecting the Influence of Welding Seams. Nerves with Constant Thickness and Height Along the Entire Length

Abstract The present study refers to a plane circular plate, provided with equidistant radial ribs, placed on one side (fig. 1), these having the same geometry of the cross section (thickness and height) along their entire length (fig.2). There is a change in the position of the neutral fiber of the ribbed plate and also in its bending rigidity, along the radius of the plate, in different cases.
