Abstract
An ATJ-S graphite annular disk of a wedge-shaped cross section is subjected to outside to inside temperature gradients of up to 3000°F from an induction heating coil. The change in internal diameter of the disk is measured with a laser tracking device and is predicted with a modification of the Jones-Nelson nonlinear material model. This model is shown to be valid for ATJ-S graphite, which is a transversely isotropic granular composite material with stress-strain behavior that is highly nonlinear, strongly dependent on temperature, and different in tension than in compression. The predicted diameter changes at three times in the same test agree with the averages of two perpendicular diameter change measurements within about 3%.
