Definition of a mechanical system
Digital simulation in the designing process of mechanical systems

However, for the sake of clarity, we can distinguish a "core": fundamental mechanics, comprising both theoretical (analytical mechanics, numerical mechanics) and experimental aspects. Around this core, there are two major fields: solid mechanics and fluid mechanics, to which numerous fields of knowledge are associated: materials, structures, mechanisms, acoustics, thermics, flows, etc.

More broadly, mechanical science touches on four main areas of human activity (figure...
