Texture independent determination of residual stress in polycrystalline aggregates using Rayleigh waves
Abstract
The Rayleigh wave velocity for a polycrystalline aggregate of cubic crystals with orthorhombic symmetry is derived. The formalism of Rod for treating the texture of polycrystalline aggregates is used. It is shown that surface wave velocity measurements can be combined with the normal shear wave birefringence technique to give a texture independent determination of the difference in principal stresses. The accuracy of the theory is demonstrated for rolled aluminum and steel plates.
