TÓM TẮT
Due to the propagation and interaction characteristics in materials of ultrasonic wave, it is widely used in the different fields such as mechanical engineering, construction engineering, etc…, especially to control quality, to detect cracks and defects in concrete construction, and be also used to identify characteristics of concrete block. It is very important to understand the propagation and interaction characteristics of ultrasound wave in isotropic and anisotropy elastic materials. The paper deals with a two-dimensional simulation of ultrasonic wave propagation in elastic materials. A mathematical model wave propagation in material media is established and numerical simulation is based on finite element method (FEM). Simulation results display two-dimensional images of wave propagation inside structures, as well as displacements, stresses and strains at specific points in the material according to space and time.
