Abstract
LONDON. Royal Society, June 2.—S. Chapman and A. E. Ludlam: A theoretical discussion of certain elastic constants of calcite and crystalline sodium nitrate. Upper limits are found theoretically for two of the elastic constants of calcite and crystalline sodium nitrate; the calculations are based on the theoretical determinations of the potential energy of these crystals in various configurations. The theoretical upper limits found are larger than Voigt's measured values for calcite but of the same order of magnitude.
