The Green-Lagrange strain does not include rigid body motion. Precisely, that is why it is very useful in large deformation analysis and other nonlinear analysis, Refers to the book:

Hi Surajitdas, Consider
Hi Surajitdas,
Consider a rigid body for example a plane motion. Give some translatory motion to this. Define initial and final co-ordinates of the body.
U = final position - initial position = U(x,y).
Calculate Green - Lagrange starin tensor => E = 1/2(GardU+(GradU)^T+GradU*(GradU)^T). This vanishies.
I hope this helps.
