Organizing and summarizing search results for youThe deformation gradient is a tensor that represents the stretching and rotation of tangent vectors. It can be expressed as F = R U or F = V R, where F is the deformation gradient, R is the rotation tensor, and U and V are the right and left stretch tensors, respectively. The deformation gradient tensor dw = F ⋅ dx, where dx is an infinitesimal line element in an undeformed solid, and dw is the vector representing the deformed line element. The relationship between the differentials, dX and dx, can be expressed in compact form as dx = FdX.3 Sources
