Introduction Definition of yield strength. Yield Strength: It is the yield limit of a metal material when it yields, i.e. the stress that resists slight plastic deformation. For metal materials without obvious yielding, the stress value that produces 0.2% residual deformation is specified as its yield limit, called the conditional yield limit or yield strength.The corresponding gage length = 2.0083 in, which is the 0.2 percent yield point.

Ultimate Compressive Strength: The maximum compressive stress a material specimen is capable of carrying is known as the ultimate compressive stress. Unlike in the case of tension, the compressive response of a specimen is a function of its cross-sectional shape and length. To eliminate these geometric effects, compressive specimens are usually designed to be very .
As I understand it, in simplist terms, tensile strength is the force required to pull a bolt apart and yeild is the force required to deform it to the point where it does not fully recover.

ASTM A36 Steel. ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon ≤ 0.25%)..
