A strain rate of 66 %/sec was used for the monkeys.
The range of strain rate used was from 0.011 to 222 %/sec.
It does not allow for differences in shear strength based on different strain rates.
Also, the strain rate may be studied and analyzed for its effect on fracture.
Another advantage to the process includes the knowledge of the new part's strain rate.
There are also fluids whose strain rate is a function of time.
So generally the critical stress will decrease with imposed strain rate.
Type A bands are often seen at high strain rate and low temperatures.
C bands are often seen at low applied strain rate or high temperatures.
However, polymers for the most part show the strain rate to be decreasing with time.
