Tensile, Compressive, Shear, and Torsional Stress
Stress, σ, is defined as the force divided by the initial surface area, σ=F/A o . This pulling stress is called tensile stress. Strain is what results from this stress. Strain, ε, is defined as the change in length divided by the original length, ε = Δ I / I o. Before we proceed further with stress and strain, let's define some other types ...

Bearing strength of concrete VS Compressive strength of concrete
American code gives a nominal value of compressive bearing as Pn=0.65 * 0.85 * f'c * A1, where f'c is the design unconfined compressive strength and A1 is direct bearing area. This can be increased if there is a larger "supporting area" A2 below the bearing area by min( 2, (A2 / A1)^0.5 ).

Surface and subsurface rolling contact fatigue
For example, in fretting fatigue the peak tensile stress causes mode I SIF higher than the threshold even at small size of the crack, and the minimum difference between Δ K I and Δ K th is reached at the El Haddad crack size itself [63], [64], eventually producing initiated non–propagating cracks for loading conditions below the fatigue limit.
