In this paper we study the averaged controllability of Ambartsumyan plate made a transversely isotropic material. Governing equations are based on assumptions particular theory anisotropic plates developed by S. A. specifically for describing deformation material with isotropy plane which, at each point plate, is parallel to its middle plane. The Green’s function approach applied express normal...

We have considered a semi-infinite crack embedded in a transversely isotropic medium and studied two special cases, one, in which the axis of symmetry is normal to the crack face and the wave incidence is arbitrary and another, in which the axis lies in the crack plane normal to the edge and the incident wave vector is also normal to the edge. The problem is of interest in Non-Destructive Evalu...
