Strength of High Speed Rotating Discs (3rd Report)

Abstract

A method of determining stresses and strains in a fully plastic rotating disc with a uniform thickness and a centre hole is developed by means of the deformation theory. Comparisons between calculated values and experimental data of the strain-distributions are made for aluminium and brass discs. The results of comparisons show that the calculated values of radial deformations are, in some degrees, less than the observed values. This discrepancy is considered mainly due to the impropriety of the assumption that the material is homogeneous and isotropic after it submitted plastic deformation.
