Thus , we can restrict the force constants to few near neighbors . In practice , one
may have to include the effect of several neighbors because the elastic
disturbances in the matrix may extend quite far . However , the number of
neighbors to be ...

Equating the coefficients of k ; ? in the corresponding elements of the matrices D (
k ) and A ( k ) , we get the following relations between the force constants and the
elastic constants A + 2D = ( 11 B + 2D = 266 E = C44 F + 2G = C44 ( 50 ) H ...

Herbert Herman. Let us consider a wave traveling in the yz plane . For this plane
the form of the dispersion relations will be the same for tetragonal and hexagonal
symmetries . Using the Set 1 for the elastic constants ( Section X ) , and p = 2 , E ...
