Abstract
A 'multiparameter' method for indirect evaluation of intrinsic anisotr opy values for prestressed engineering materials is discussed. The pro posed method is based on simultaneous measurement of both the velocity of elastic waves and the parameters, characterizing the frequency dis persion and/or attenuation. Preliminary experimental demonstrations of the feasibility of such methods for common engineering materials are presented. (C) 1998 Elsevier Science B.V.
