Hello,

 
I'm a little bit confused with a naming convention of strain rates of Johnson-Cook plasticity and damage model in Abaqus. In J-C equations there are two parameters:  

• ε.0 (epsilon dot zero) known as a reference strain rate which has the value of 1 s-1,
• ε. (epsilon dot) known as the plastic strain rate or the effective strain rate [s-1].

In Abaqus (Edit Material window), there are two parameters with the same(?) name:

Hi there,

would you please tell me how can I use or calculate the effective strain rate or strain rate in ABAQUS subrotine?

 thank you!

I would like to simulate the response of a metal to a slow strain rate test. So I need to impose the strain.

It is possible to impose strain with abaqus or can we just apply load?

Thank you
