In continuation to our previous work on 5xxx series Al alloys
Experimental and numerical investigations of yield surface, texture, and deformation mechanisms in AA5754 over low to high temperatures and strain rates node/14353
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:
They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid. Video was recorded at Barcelona, Spain.
