This document discusses the relationships between different elastic constants - Young's modulus (E), shear modulus (G), and bulk modulus (K). It defines each constant: E is the ratio of stress to strain under tension or compression, G is the ratio of shear stress to shear strain, and K is the ratio of normal stress to volumetric strain. It notes that the units of measurement are the same for all elastic constants, and that derivations of the relationships between E, G, and K will follow.

- 1. STRENGTH OF MATERIALS MODULE :- 01 TOPIC :- RELATION BETWEEN ELASTIC CONSTANTS(E,G & K) BY:- 1. MR.YOGENDRA KUMAR 2. MR.BHUPENDRA KUMAR SARASWAT 3. MR.MAHENDRA KUMAR SAHANI 4. MR.AKASHDEEP YADAV BE READY FOR DERIVATION OF E, G, AND K
- 2. RELATION BETWEEN DEFFERENT ELASTIC CONSTANTS 1. YOUNG'S MODULUS(E):- Its also known as hooke's law. according to this law the stress is directly proportional to strain upto proportional limit. 2. MODULUS OF RIGIDITY(G):- It is the coefficient of elasticity for a shearing force.It is defined as the ratio of the shear stress(q) to the shear strain(ф). shear modulus q G 3. BULK MODULUS(K):- It is the ratio between direct stress to the volumetric strain of a material up to elastic limit. ve p K Note:-Unit of all elastic constant will be same N/mm2 , MPa. GPa. Etc.
