Introduction to Mechanics of Materials
Mechanics of materials, often referred to as strength of materials, is a subject that examines how materials deform under various types of loading. The analysis involves:
- Stress: The internal resistance of a material to deformation, measured as force per unit area.
- Strain: The measure of deformation representing the displacement between particles in a material body.
- Elasticity: The ability of a material to return to its original shape after being deformed.
- Plasticity: The permanent deformation of a material after the removal of the applied load.
