Summary

The discovery and evolution of computing and technological tools over time has undoubtedly been an important aid for scientists, researchers, engineers and general professionals involved in the field of science. Increasingly efficient machines made their appearance in the field of science. Software capable of solving problems that until recently were impossible to solve were created. While recently artificial intelligence has entered the sciences in a big way, changing the technological map of the future . This development has led people to the need to create software that will be able to predict the results of an experimental study first carried out either because of high study costs, or to minimize the time of conducting the experiment. One of these programs was the catalyst for the writing of this thesis, as it deals with the modelling of an experiment in a computer program. The aim of the study is, after a detailed design of a metallic container and the use of finite elements through the Comsol Multiphysics software, to find theeigenfrequencies generated during the impact of the object and their corresponding eigenmodes. Finally, in order to verify the results collected by the program, an experimental confirmation will be made using a piezoelectric crystal.
