YIELD POINTThe load per unit of original cross section at which, in soft steel, a marked increase in deformation occurs without increase in load. YIELD STRENGTH (YS)The stress (load/area) at which the metal changes from elastic to plastic in behavior, i.e., takes a permanent set. YOUNG’S MODULUSThe coefficient of elasticity of stretching. For a stretched wire, Young’s Modulus is the ratio of stretching force per unit cross-sectional area to the elongation per unit length. The values of Young’s Modulus for metals are of the order 10 12 dynes per square cm. (See Modulus of Elasticity) MTP Incorporated Phone: (805)
