Question

what are elastic constants? ​

Answer 1

Elastic constants are the parameters expressing the relation between the stress and the strain on the materials within the stress range that the materials exhibit elastic behavior

Answer 2

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)
