Question

What are the three elastic constants of materials?

What's the relationship between them?​

Answer 1

Answer:

There are three elastic constants;

Normal stress/ Normal strain. = Young'smodulus or Modulus of elasticity (E)

Shear stress/ Shear strain. = Shear modulus or Modulus of Rigidity (G)

Direct stress/ Volumetricstrain. = Bulk modulus (K)
