Continuum Mechanics is the study of the response of the matter on a macroscopic scale to different loading conditions, neglecting the structure of the matter on the smaller scale (i.e., molecular scale). It brings out the general principles common to all media and discusses the assumptions for developing constitutive equations of idealized materials (e.g., solid and fluid). The developed fundamentals can be applied to engineering problems such as elasticity, viscoelasticity, plasticity, linearly viscous fluid, etc.
