abstract = "The residual stresses modify slightly the mechanical properties of materials. Ultrasonic waves make up a not destructive method to investigate these stresses. The theory of acoustoelasticity leads to a generalised Christoffel equation able to describe the propagation of ultrasonic waves
in these materials. This approach makes use of elastic constants of second and third order of materials at the natural state, and residual stresses. The present work deals with the distribution of acoustoelastic effects in cubic materials under axial stresses. The relative variations of several
physical parameters to know slowness, energy speed, birefringence are examined in high symmetry planes in order to characterize the residual stresses present in cubic materials in different direction. ",
