Compressive strength is the maximum compressive stress that, under a gradually applied load, a given solid material can sustain without fracture. The formula for calculating compressive strength is: CS = F / A Where in compressive strength (CS) is equal to the force (F) at the point of failure divided by the cross sectional area.
