Ultrasonic tomographic imaging of defects in industrial materials

摘要: Ultrasonic tomography has been fairly widely applied for imaging of inhomogeneities in isotropic materials, particularly the medical field, however, little success made its application to industrial materials. This is largely due complex nature ultrasonic wave propagation these anisotropic The three dimensional characteristics materials have thoroughly studied single crystals and also recently different composites [1,2,3]. Understanding provides theoretical background developing appropriate tomographic methods
