Description

It is well known that crystallographic texture not only modifies the elastic constants of polycrystalline aggregates at (unstressed) natural states but also affects their acoustoelastic coefficients when the aggregates are stressed. While exact knowledge about the effects of texture on acoustoelastic coefficients has hitherto remained wanting, such effects are usually assumed to be negligible and are ignored in practical applications of acoustoelasticity (cf. [1] for example). Concerning this common practice, Thompson et al. [2] have urged caution: Care must be taken when [this] assumption is made since the influence of texture on acoustoelastic constants is stronger than its influence on elastic moduli or velocities.

Explicit Formulae Showing the Effects of Texture on Acoustoelastic Coefficients
