Intact Limestone can have a Young's modulus (E) ranging from:
9 GPa - 80 GPa.A,B
Poisson's ratio (v) for intact specimens varies from between:
0.2 - 0.3.B
Bulk modulus (K) derived from the above values using the following relation:
K = E / (3(1-(2v))
Bulk Modulus ranges from:
5 GPa - 66.67 GPa
Shear modulus (G) derived from the above values using the following relation:
G = E / 2(1+v)
Shear modulus ranges from:
3.5 GPa to 33.33 GPa
Limestone is a natural earth material and so significant variability in stiffness properties may occur, as such ranges of values are commonly quoted for the strength of rock and other geotechnical materials. Ideally therefore the user would have access to specific lab test data for the rock type in question.

The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.

Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
1. Young's modulus of elasticity, E, also called elastic modulus in tension 2. Flexural modulus, usually the same as the elastic modulus for uniform isotropic materials 3. Shear modulus, also known as modulus of rigidity, G ; G = E/2/(1 + u) for isotropic materials, where u = poisson ratio 4. Dynamic modulus 5. Storage modulus 6. Bulk modulus The first three are most commonly used; the last three are for more specialized use
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.
The Young modulus and storage modulus measure two different things and use different formulas. A storage modulus measures the stored energy in a vibrating elastic material. The Young modulus measures the stress to in still elastic, and it is an elastic modulus.
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
The elastic modulus of shale is between 1-70 GPa
it depends on modulus of elasticity / young's modulus,,,,,,,which is ratio of stress and strain under elastic limit
Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.
Every material has its elastic modulus, and the speed of sound is proportional to the square root of the elastic modulus of that material.

That is the shear modulus, G, related to Young elastic modulus ,E, as G = E/(2(1+u)) where u is Poisson ratio
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
The modulus of elasticity is the slope of the linear portion of the curve (the elastic region).
