Compressive Strength:- Compressive strength is an effective way of measuring how much load a surface or material can bear. for this sort of strength is performed by exerting force downward on top of the objectequal and opposite force exerted upward on the bottom when L/D > 5,Buckling when L/D > 2.5, Shearing when L/D > 2.0 and friction is present at the contact surfaces,Double barrelling when L/D < 2.0 and friction is present at the contact surfaces, Barrelling when L/D < 2.0 and no friction is present at the contact surfaces, Homogenous compression. Compressive instability due to work-softening material. The compressive stress formula is:- CS = F ÷ A Compressive Strength = Load / Cross-sectional Area where  CS  is the compressive strength F is the force or load at point of failure and  A  is the initial cross-sectional surface area
