抄録

This paper describes an approximate theory determining stresses and strains in a fully plastic rotating disc having a uniform thickness and a solid center, without any aid of trial-and-error method of calculation. In the first place, the approximate equations showing stress-distribution, strain-distribution and the relation between the number of revolutions and deformations of the disc were derived, assuming linear distribution of nominal strain and using some approximations. Then, this theory was examined by making use of the experimental results in discs of brass, aluminum, and mild steel. As the result of the examination, it was considered that this approximate theory might be applicable to the calculation of plastic deformations in such a disc as mentioned above.
