Max. Shear Rate

This result shows the recorded peak value of shear rate of each element during the filling stage. Note that the maximum shear rate values shown in this result are not necessarily in the same time step.

 

Shear rate is the rate of shear deformation of the material during the polymer processing. Shear rate distribution is related to the variation of velocity gradient and molecular orientation. High shear rate tends to drastically deform molecular chains even to break and then weaken the strength of product. Viscous heating due to high shear rate also should be noticed.
