is called a modified '''plastic velocity gradient''' and is defined in an intermediate ([[compatibility (mechanics)|incompatible]]) stress-free configuration. The symmetric part ('''''D'''''^p) of '''''L'''''^p is called the '''plastic rate of deformation ''' while the skew-symmetric part ('''''W'''''^p) is called the '''plastic spin''':

:<math>

\boldsymbol{D}^p = \tfrac{1}{2}[\boldsymbol{L}^p +(\boldsymbol{L}^p)^T] ~,~~

\boldsymbol{W}^p = \tfrac{1}{2}[\boldsymbol{L}^p -(\boldsymbol{L}^p)^T] \,.

Typically, the plastic spin is ignored in most descriptions of finite plasticity.
