The goal is to provide knowledge of the fundamental, unifying concepts of the mechanics of continua as a a core course for graduate study in Mechatronics Engineering. The aim is to provide a physically based but primarily analytical and theoretical introduction to the subject as preparation for more advanced study in solid and fluid mechanics and the reading of current literature in these fields. Tensors of stress and deformation. Balance and conservation laws, thermodynamic considerations. Examples of linear and non-linear constitutive relations. Field equations and boundary conditions for solids and for fluid flow.
