Does anyone who has previously worked on MSC Marc worked with the concept of element activation and deactivation...?

I need to do a simulation wherein a hole is required to be punched in an alloy steel bar.

The issue is that I am not sure as to how to go about this.

If there is anyone who can guide me through this ..I would appreciate it..!!

Krunal. 

Hie,
1] I am Krunal, currently pursuing my masters for University of Sheffield, wherein for my thesis I require to simulate the forging process for commercial vehicle Anti-roll bars using MSC MARC software. 2] I require the flow stress curves for the material 51CrMoV4 at varying temperatures ( approx 850 - 1400 deg celcius ) and varying strain rates ( approx 0.01 to 50 per second). However I am unable to find it....!!

Dear iMechanicians,

I wonder if anybody knows how to get an op2 file (MSC.Nastran) from MSC.Marc. Is something like that possible? Or do you know some available converter? Potentially, fil or odb file from ABAQUS or rst file from ANSYS could help as well. But I would expect there some way within the MSC product family...

Thanks a lot for any idea.

Greetings all,

I am trying to use gerenalized maxwell viscoelastic model for polyimide polymer films (Kapton) in MSC Marc (or ABAQUS). I have never used the prony series representation of the maxwell model (hereditary integral approach). Has anyone ever used MSC Marc to incorporate the prony series relaxation to the material? or ABAQUS? Here is my game plan for doing this:

 1. I have the uniaxial relaxation curve for the polymer film, I obtain elastic modulus as a function of time for this model by curvefitting the relaxation curve and then obtain the prony series coefficients.
