Question

what are the elastic constant

Answer 1

Different types of stresses and their corresponding strains within elastic limit are related which are referred to as elastic constants. The three types of elastic constants are: Modulus of elasticity or Young's modulus (E), Bulk modulus (K) and. Modulus of rigidity or shear modulus (M, C or G).

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.
