elastic modulus noun
: the ratio of the stress in a body to the corresponding strain
First Known Use of ELASTIC MODULUS
elastic modulus noun (Concise Encyclopedia)
In materials science and physical metallurgy, any of various numbers that quantify the response of a material to elastic or springy deflection. When tensile stress is applied to a material, the resulting strain is determined by Young's modulus (see Thomas Young), a constant defined as the ratio of the stress in a body to the corresponding strain. It has dimensions of (force)/(length)2 and is measured in units such as the pascal or newton per square meter (1 Pa = 1 N/m2), dyne/cm2, or lbs per sq in. (psi). See also elasticity.
