WHAT ARE THE VALUES OF MODULUS OF ELASTICITY
Feb 13, 2015 Poisson’s Ratio of Rock. Poisson’s ratio measures the ratio of lateral strain to axial strain at linearly elastic region. For most rocks, the value of Poisson’s ratio ranges in between 0.15 to 0.40. Typical values of modulus of elasticity of some common are given in the table below. Values of Poisson’s Ratio for Some Common Rocks
