For example, if you push a cylindrical item in two opposed directions, the compressive stress equals the amount of force exerted divided by the area of the base of the cylinder. The difference between tensile stress and von Mises stress is that tensile stress only considers the tension (pulling) force applied to a point, while von Mises stress considers all components of the stresses acting on a given point – tensile, compression, and shear. Since the stress across a beam section varies from compression to tension, there is a location at which stress is equal to zero. Compressive stress is treated as negative in calculations. This is different from tensile stress, which occurs when forces pull a material apart, stretching it instead of compressing it. At low stresses, strain is elastic, and the material returns to its original shape when stress is removed. Tensile stress and compressive stress are both different in that one leads to the stretching of an object, and the other leads to the compression of an object.
