Asymptotic equipartition of energy for equations of elasticity
James T. Sandefur, Lawrence Edward Payne · Mathematical Methods in the Applied Sciences · 1983
Abstract In this paper we give a review of the equipartition of energy results of Goldstein and Sandefur [3], [4], [5] as well as proving a new result in the case of a particular fourth order equation. These results are then applied to the equations of elasticity to give a weak asymptotic orthogonality for the shear and pressure waves. In the case of boundary value problems in the interior of a bounded domain we get weak asymptotic orthogonality in the average.
