Greetings,

I wrote the following subroutine to extract nodal stress values. It perfectly writes down the nodal stresses in MSC.Marc installed for Linux; however, when I try to implement this subroutine in MSC.Marc installed for Windows using intel(R) Visual Fortran compiler, error "forrt1: severe <157>: Program Exception - access violation" occurs.

The subroutine is:

subroutine impd(lnode,dd,td,xord,stnod,f,v,a)

Rayleigh damping and numerical damping. (Ls-Dyna vs Msc.MARC)

Hi to all of you!

I have problems about dampings.

I have used Msc.MARC to simulate a Hopkinson bar experiment. We usually use a

"numerical damping" in these analysis.

As you know, MARC is a implicit FEM and it takes a lot of time to complete each

simulation.

So, I want to use Ls-Dyna, but I have the problem of damping. In Ls-dyna, we use

the Raylegh damping: there are 2 coefficients that multiply the matrix of

stifness and mass.

Is there any relation between these two kinds of dampings?

Simulating Hole punching operation using MSC Marc

Submitted by kruzster on Fri, 07/09/2010 - 16:31

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..!!

Regards,

Krunal.

Flow Stress Curves for 51CrMoV4 material at varying temperature and strain rates

Submitted by kruzster on Sat, 03/27/2010 - 11:09

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....!!

op2 from MSC Marc?

Submitted by pragtic on Wed, 12/03/2008 - 17:25

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:
