| Abstract: | Two procedures for the computation of the elastic constants (trigonal system) from measured values of elastic wave velocities are discussed. The simplified procedure first used by Bhimasenachar is incorrect in principle although, in very rare cases, it may lead to only small numerical errors. A new procedure is mentioned which simplifies the use of the Christoffel equations in an exact way. |
