R. Ed. CRC Press Boca Raton FL 2001 p. 12-37 with additions from the Handbook of Optics Vol. 2 McGraw-Hill New York 1999 and the Handbook of Laser Science and Technology Vol. IV and Suppl. CRC Press Boca Raton FL 1995 . The elastic constants Cij for single crystals are given in units of 1011 N m2 equivalent to 100 GPa or 1012 dyn cm2 . The values are for room temperature. A useful compilation of published values from various sources may be found in Simmons G. and Wang H. Single Crystal Elastic Constants and Calculated Aggregate Properties A Handbook 2nd edition The MIT Press Cambridge MA 1971 . Temperature and pressure coefficients of the elastic constants for many materials are included in Landolt-Bornstein New Series III 11 Hellwege . and Hellwege A. M. Eds.
