description: The subject of the graduate qualification work is âNumerical simulation of propagation of an ultrasonic elastic wave generated by a piezoelectricâ. In the given work, using the ANSYS finite element analysis software system, we numerically simulate the generation and propagation of a shear ultrasonic wave in an elastic material. During the study, the following problems were solved: 1. Construction of a finite element model of a piezoelectric sensor and an elastic non-stressed material. 2. Numerical simulation of the propagation process of an ultrasonic wave initiated by a piezoelectric element in an elastic material. 3. The study of the influence of the presence of cracks and voids in the ma-terial on the acoustic wave propagation pattern. 4. Investigation of the influence of the presence of a preliminary stress state in the material on the speed of propagation of an acoustic wave. The paper presents a finite element model, which allows to describe numerically the process of generation of a shear ultrasonic wave by a piezoelectric and the process of its further propagation in elastic material. In the case of an unstressed elastic material, this model allows to visualize the propagation of an ultrasonic wave in the material and register the time for which the reflected wave will return to the sensor. In the work it was found that for the analysis of materials in which a preliminary stress-strain state is observed, this model requires refinement and additional research.
