Compressive Stress - Definition, Formula, Units, Dimensions and FAQ

Compressive stress arises from squeezing the material while tensile stress is due to the stretching of the material. Compressive stress can be defined as the push provided to the body by external force application which results in a change of shape and size while tensile stress can be defined as the pulling of the body to change its shape and size.
