simulation traction test of a composite material test

[manliore]

Hello everyone,
I write to ask you how to proceed on hypermesh (pre-processor) and ls-dyna (solutor) a simulation of a traction test for high deformation speeds for the master thesis. I have realized the experimental tests of these tests and now I would like to see if I get the same results in the numerical simulation. Unfortunately, however, I cannot model composite materials on hypermesh, as I have always worked with other types of materials.
As for the constraints, I thought I'd go and set inks on one side to the whole area of the sample where there are grabs, while on the opposite side to set a certain point shift speed. Do you agree?
You could help me out, please.

I answer only for the part of constraints because I have never treated the composites and not even the solutor you mentioned.
the test is the one provided by the norms and anyway equal to the laboratory one.
Surely you will have used a machine with screw jack or a hydraulic galdabini.
the requirement as a rule is that the test remains axially aligned in the direction of the load, therefore on one side will be gripped and then framed. on the opposite side apply axial force with speed law. You could improve the simulation with a sleeve bond on the side of the force, so as to correct any radial spur values of the simulation.
