Dear Arshad,
I suspect you can get by with a static analysis if you are si=
mply trying to
remove a part from a mold. If you are introducing impact to =
try to remove
the part, then you may need to consider an explicit analysis.=
The real
answer comes down to the time scale over which the part is remove=
d and
corresponding inertia forces. If "quasi-static" removal, go with
Abaq=
us/Implicit.
You can enforce a velocity by specifying a displacement to oc=
cur over a
given time. The time over which a load occurs is defined when yo=
u are
setting up your steps. If you conduct a static analysis, I don't thin=
k
velocity is pertinent to the solution since inertial forces are neglected=
...
The time step simply tells Abaqus the time over which a load is applied.=
I
think it doesn't much matter what the time step is for a quasi-static
st=
ructural analysis.
Regards,
Travis
