| Continuum mechanics The study of the physics of continuous materials |
Solid mechanics The study of the physics of continuous materials with a defined rest shape. |
Elasticity Describes materials that return to their rest shape after applied stresses are removed. | |
| Plasticity Describes materials that permanently deform after a sufficient applied stress. |
Rheology The study of materials with both solid and fluid characteristics. | ||
| Fluid mechanics The study of the physics of continuous materials which deform when subjected to a force. |
Non-Newtonian fluid Do not undergo strain rates proportional to the applied shear stress. | ||
| Newtonian fluids undergo strain rates proportional to the applied shear stress. | |||
