##### THE DEFORMATION MODULUS OF ROCK MASSES - ,

Know More2 ON DEFORMATION AND ELASTIC MODULI 21 Definitions Deformability is characterized by a modulus describing the relationship between the applied load and the resulting strain The fact that jointed rock masses do not behave elastically has prompted the usage of the term modulus of deformation rather than modulus of elasticity or Young's modulus...

## Bulk Modulus – My DataBook

Know MoreThe formula for bulk modulus is: (1) Where V = initial volume, dP = change in pressure, dV = change in volume K can be alternatively calculated if the Youngs Modulus (also known as the Modulus of Elasticity) and the Poisson’s Ratio of the material are known Here, (2) Where E = Youngs Modulus and = Poisson’s Ratio Bulk Modulus ,...
