Grüneisen Tensor for Anisotropic Materials

摘要

The Grüneisen parameter has been defined as the pressure response in a material to a change in internal energy with the strains held constant. The Grüneisen parameter does not account for the oriented response of anisotropic materials; the Grüneisen tensor is developed to account for this response. The Grüneisen tensor is stated explicitly for several crystal classes. Alpha‐quartz is considered as an example of an anisotropic material, and specific values for its Grüneisen tensor are presented.
