1modulus — A coefficient expressing the magnitude of a physical property by a numerical value. [L. dim. of modus, a measure, quantity] bulk m. SYN: m. of volume elasticity. m. of elasticity a coefficient expressing the ra …
2bulk modulus — Physics. a coefficient of elasticity of a substance, expressing the ratio between a pressure that acts to change the volume of the substance and the fractional change in volume produced. [1905 10] * * * Numerical constant that describes the… …
3Bulk modulus — Incompressibility redirects here. For the topic in fluid dynamics, see Compressibility. Illustration of uniform compression The bulk modulus (K) of a substance measures the substance s resistance to uniform compression. It is defined as the… …
4shear modulus — Physics. a coefficient of elasticity of a substance, expressing the ratio between the force per unit area (shearing stress) that laterally deforms the substance and the shear (shearing strain) that is produced by this force. Also called modulus… …
5Young's modulus — In solid mechanics, Young s modulus (E) is a measure of the stiffness of an isotropic elastic material. It is also known as the Young modulus, modulus of elasticity, elastic modulus (though Young s modulus is actually one of several elastic… …
6Elastic modulus — An elastic modulus, or modulus of elasticity, is the mathematical description of an object or substance s tendency to be deformed elastically (i.e., non permanently) when a force is applied to it. The elastic modulus of an object is defined as… …

8Young's modulus — Physics. a coefficient of elasticity of a substance, expressing the ratio between a stress that acts to change the length of a body and the fractional change in length caused by this force. [1860 65; named after Thomas YOUNG, who derived it] * *… …
9Section modulus — In structural engineering, the section modulus of a beam is the ratio of a cross section s second moment of area to its greatest distance from the neutral axis.The section modulus is directly related to the strength of a corresponding beam. It is …
