WebThe Green strain tensor, E, is based on the deformation gradient as follows. E = 1 2(FT ⋅ F − I) Recall that FT ⋅ F completely eliminates the rigid body rotation, R, from the problem because FT ⋅ F = (R ⋅ U)T ⋅ (R ⋅ U) = UT ⋅ RT ⋅ R ⋅ U = UT ⋅ U WebThe stress tensor which naturally derives from Edescribes the surface force measured in the initial space with respect to the initial area: dF0=da = @E=@", it is known as the second Piola-Kirchho stress. Then in order to nd the Cauchy stress measured fully in the target space: ˙= dF=dA, we need to transform the surface force and the area as
