The correct relations between elastic constants:
E = 2G(1+u) or E = 2C ( 1 + 1/m).
E = 3k( 1-2u) or E = 3K (1 - 2/m).
E = 9KG/(3K+G) or 9KC/(3K + C).
u = (3K- 2G)/(2G+6K) or 1/m = (3K - 2C)/(2C+6K).
So options B and E are incorrect.
E = 2G(1+u) or E = 2C ( 1 + 1/m).
E = 3k( 1-2u) or E = 3K (1 - 2/m).
E = 9KG/(3K+G) or 9KC/(3K + C).
u = (3K- 2G)/(2G+6K) or 1/m = (3K - 2C)/(2C+6K).
So options B and E are incorrect.
