yield strength : the strength at which a small amount of permanent (plastic) strain occurs, usually 0.1% or 0.2%, and most frequently measured in MPa or psi

Young’s modulus: [Thomas Young (1773-1829) English physician and physicist] eponym for the constant of proportionality expressed in the stress-strain plot as the slope in the elastic region where elastic recovery occurs upon release of the stress inducing the strain; usually given the symbol E. A higher modulus (GPa, psi) denotes a greater stiffness or material rigidity. Also termed MODULUS OF ELASTICITY
