The similarity to the better known optical birfrengence became obvious by experimental investigations using a solid under applied stress as well as by the theoretical treatments of the acousto-elastic effects. The major applications of the acoustic birefringence effect are the characterisation of stress states in the bulk of components and the characterisation of texutre and testure-related properties of rolled parts and semiproducts. Both stress and texture cause an elasti anisotropy of the component. The birefringence of a lineary polarised shear wave, polarised parallel to each of the two principal axes, respectively, yield quantitative results. The state of the art is illustrated by two application of industrial relevance.enAnisotropieanisotropybirefringencedeep drawabilityDoppelbrechungEisenbahnelastic constantselastische Konstanterailway wheelrolled productSpannungStress stateTexturtexturetexture coefficientTiefzieheigenschaftTiefziehfähigkeitTransversalwelleUltraschallultrasoundWalzprodukt620658670535journal article
