Also known as unit deformation, strain is the ratio of the change in length caused by the applied force, to the original length. where δ is the deformation and L is the original length, thus ε is …
- During the subject of Mechanics of Materials (Strength of Materials) the investigations are limited only the theory of linear elasticity. The elasticity is the mechanics of elastic bodies. It is known that solid bodies change their shape under load. The elastic body is capable to deform elastically. The elastic deformation means that the body under...
