This type of stress may be called (simple) normal stress or uniaxial stress; specifically, (uniaxial, simple, etc.) tensile stress. [13] If the load is compression on the bar, rather than stretching it, the analysis is the same except that the force F and the stress σ {\displaystyle \sigma } change sign, and the stress is called compressive ...
Engineering stress and engineering strain are approximations to the internal state that may be determined from the external forces and deformations of an object, provided that there is no significant change in size. When there is a significant change in size, the true stress and true strain can be derived from the instantaneous size of the object.
A stress field is the distribution of internal forces in a body that balance a given set of external forces. Stress fields are widely used in fluid dynamics and materials science . Consider that one can picture the stress fields as the stress created by adding an extra half plane of atoms to a crystal .

In geology, stress is defined as a force applied to a material. There are 4 types of stresses that rocks are subject to. First of which is when rock is pushed down by the weight of all the rocks above it, preventing it from moving. This is called confining stress and is predominant deep beneath the Earth's surface. The second type is compression.
