Continuum mechanics

Definition

Continuum mechanics is a branch of mechanics that deals with the behavior of materials modeled as continuous masses rather than discrete particles. It focuses on understanding how materials deform and flow under various forces, taking into account the internal structure and interactions at different scales. This approach is particularly useful in biomimetic materials, as it allows researchers to bridge the gap between microscopic structures and macroscopic material properties.
