ON THE BENDING OF CIRCULAR PLATES IN THE PLASTIC DEFORMATIONS FIELD (RIGID-PLASTIC MATERIALS) PART II: ELASTIC-PLASTIC DEFORMATIONS OF THIN CIRCULAR PLATES SUBJECTED TO BENDING (RIGID-PLASTIC MATERIALS)

Abstract

The circular plate of small thickness is subjected to uniform distributed loads, q=q(r), perpendicular to the mean plane. The basis hypothesis in the classic theory of elastic bending of circular plates is a general feature. Under these circumstances they remain valid in the case of bending, until the plastic deformations field. In order to simplify the calculus, one studies a circular plate made of a rigid-plastic material. In this case, the plate will be not deformed until the limit load beard by the material is reached
