Apr 01, 1995 · A power equation was derived by Martin and Haynes for Young's modulus of porous materials and was later used to analyse the data of several other types of materials also. E = (1 - aP2/3). (10) Here the exponent of the term P is 2/3, because the values for the slope "a" involves 2/3 power of number of voids per unit area. 188.8.131.52.
What Is Young's Modulus? Definition and EquationNov 13, 2019 · Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed.
Young's Modulus - concrete.nist.gov NISTSince virtually all solid materials have a solid Poisson's ratio in the range 0 s 0.5, we conclude that the Young's modulus can practically be regarded as being independent of the solid Poisson's ratio. As s decreases, the maximum variance increases to 15 % at s = -0.3. In the graph, we also show the SCM for spherical inclusions.
