Continuum mechanics

Definition

Continuum mechanics is a branch of mechanics that deals with the analysis of physical properties of materials modeled as continuous masses rather than discrete particles. This approach is essential in understanding how materials deform and respond to external forces, especially in contexts where the material behaves in a uniform manner on a macroscopic scale. It helps in predicting the behavior of materials during processes like deposition and doping, which are crucial in manufacturing thin films.
