bulk modulus of elasticity
bulk modulus of elasticity[¦bəlk ′mäj·‚·ləs əv i‚las′tis·əd·ē] (mechanics) The ratio of the compressive or tensile force applied to a substance per unit surface area to the change in volume of the substance per unit volume. Also known as bulk modulus; compression modulus; hydrostatic modulus; modulus of compression; modulus of volume elasticity. bulk modulus of elasticity, modulus of volume elasticityA number expressing a material’s resistance to elastic changes in volume; the ratio between a pressure that acts on a material (to change its volume) and the fractional change in volume so produced, within the elastic limit of the material.MedicalSeemodulus of volume elasticity |
