The Rare Earth

Finite strain theory is used to obtain expressions for the change in various measured elastic constants as a function of applied magnetic field for cubic ferromagnets. Using available data on magnetic anisotropy and magnetostriction, estimates are given for the size of effects that may be expected to be observed in the rare earth – iron cubic Laves phase compounds RFe2 (R = Tb, Dy, Ho, Er, and Tm). The fractional changes in the measured elastic constants for transverse waves are expected to be as large as 10−2 at room temperature.

Theoretical Results

AbstractThe rolling of a ball on a horizontal deformable surface was investigated under the assumptions that the ball was a rigid sphere and the surface was elastic. Finite strain theory was used to develop theoretical results which were found to match observations well in cases where the ball and surface involved were such as to ensure no slipping at the region of contact, including a lawn bowl rolling on a grass rink and a billiard ball rolling on carpet. The theory did not match well the behaviour of a golf ball on a grass green because the ball was too light to enforce the no-slipping condition.
