Micromechanics of composites/Average velocity gradient in a RVE
Average Velocity Gradient in a RVE
The time rate of the deformation gradient is given by
The average time rate of the deformation gradient is defined as
Following the same procedure as in the previous section, we can show that
The velocity gradient () is given by
where is the velocity.
The average velocity gradient in a RVE is defined as
Note that only if .
