A disc with hyperbolic profile is often used in steam turbine practices. In the previous paper (5th report), the principal stresses produced in the disc are obtained and the limiting curves of its failure are deduced using the various theories related to the failure of materials which are commonly recognized to date and are compared with each other. In the present paper (6th report) the displacements and strains are obtained in order to examine the deformation of disc precisely ; namely in (1) the tangential displacement that measures the twist of dise, in (2) the radial displacement that is a measure of increase of a radius, in (3) the radial and hoop normal strains, in (4) the two principal strains in the plane of disk, in (5) the axial principal strain which indicates the change of disc thickess, in (6) the maximum shearing strains that have a close relatiouship to the maximum shearing stresses, are studied. The results of our mumerical calculations of stress and strain and displacement may fully be reported later.
