### STUDY OF THE RELATION BETWEEN THE STATIC AND …

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.

Discontinuity is the main factor affecting the stress–strain relationship of rock mass. Based on the statistical parameters of the fracture network of rock mass and combining them with the strain energy theory from continuum and fracture mechanics, the elastic stress–strain relationship of fractured rock mass is proposed and its elastic modulus is derived.

Young's modulus, numerical constant, named for the 18th-century English physician and physicist Thomas Young, that describes the elastic properties of a solid undergoing tension or compression in only one direction, as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original length. Young's modulus is a measure of the ability of a material to ...

Feb 13, 2015· First of all, (kg/cm^2)*10^5 is not the correct unit for Young's modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9.
