Study of Some Problems of Wave Propagation in Some Smart Materials and its Numerical Treatment

Abstract

The propagation of waves in smart (intelligent) materials (such as piezoelectric media and/or thermoelastic media with thermal relaxation times) has been become a topic for a lot of investigations in recent years. These investigations are considered to be important because of their possible extensive applications in various branches of science and technology. They also have a lot of applications in many natural scientific fields such as: astrophysics, geophysics, seismology, acoustics, radio electronics, communications and computer technology. The principal aim of this thesis is to investigate and find solutions of some problems associated with wave propagation in piezoelectric or thermoelastic media under the effect of thermal relaxation times by using some numerical methods. It consists of five chapters, Arabic abstract, English summary and a list of references.
