Stress is expressed as the internal forces on a body per unit cross-sectional area of a body, '''σ = F / A'''. It is measured in SI units, '''N/m<sup>2</sup>'''. The deformation due to the applied stress is called as [[strain]]. |

In an axially loaded object with a discontinuity in it, the stress trajectories of the stress distribution will not be uniformly distributed. These trajectories tend to get concentrated at the edges of the discontinuity. This is known as stress concentration. | In an axially loaded object with a discontinuity in it, the stress trajectories of the stress distribution will not be uniformly distributed.
