Computation of Mean Debye Temperature of Cubic Crystals from Elastic Constants

摘要: An improved method is presented for computing the mean Debye characteristic temperature of cubic crystals from elastic constants. It based upon an evaluation distribution in solid angle roots equation which describes propagation plane acoustic waves crystal, and otherwise employs a device due to Hopf Lechner. The end result given simple closed expressions present no computational difficulty. uncertainty computed value approximation made order 0.1 percent when anisotropy factor crystal as large 4.
