Simple shear

In fluid mechanics, simple shear is a special case of deformation where only one component of velocity vectors has a non-zero value:

$\ V_x=f(x,y)$

$\ V_y=V_z=0$

And the gradient of velocity is constant and perpendicular to the velocity itself:

$\frac {\partial V_x} {\partial y} = \dot \gamma$ ,

where $\dot \gamma$ is the shear rate and:

$\frac {\partial V_x} {\partial x} = \frac {\partial V_x} {\partial z} = 0$

The deformation gradient tensor $\Gamma$ for this deformation has only one non-zero term:
