3.18 Deformation Gradient

Previous:  Problem 3.56

Let us revisit the concept of deformation gradient, which defined the differential of deformed configuration with respect to undeformed one. Recall that . In terms of spatial  coordinates  

 

Thus

* is the deformation gradient at .

In indicial notations,

Since

Thus
