### Solid Mechanics Basics Tutorial - Lecture Notes On Solid Mechanics

Solid mechanics plays a key role in Engineering Design. Solid mechanics Concepts is very handy in Engineering Analysis. CAE software's works based on this theory which is programmed in special way to find the solution for engineering design. But its better for Engineers to know How CAE/FEA works, that is role of  Solid Mechanics in Engineering Design.

Solid mechanics is the branch of physics and mathematics that concerns the behavior of solid matter under external actions (e.g., external forces, temperature changes, applied displacements, etc.). It is part of a broader study known as continuum mechanics.

A material has a rest shape and its shape departs away from the rest shape due to stress. The amount of departure from rest shape is called deformation, the proportion of deformation to original size is called strain. If the applied stress is sufficiently low (or the imposed strain is small enough), almost all solid materials behave in such a way that the strain is directly proportional to the stress; the coefficient of the proportion is called the modulus of elasticity or Young's modulus. This region of deformation is known as the linearly elastic region.
