In graphite, we have planes of carbon atoms. The carbon atoms in the plane are held together by very weak forces. What kind of elastic behaviour do you expect from graphite? |
|
Answer» Due to weak attractive forces between the carbon atoms, the atomic planes easily get laterally displaced with respect to each other, when a small tangential stress is applied, since Modulus of rigidity (η) = tangential stress/shear strain graphite possesses a small value of the modulus of rigidity |
