Hello fellow researchers,
I am working on dynamic loading of a simply supported beam (Using Split Hopkinson Pressure Bar SHPB). I use a elastoViscoplastic material model for my sample. After a period of time, LS-Dyna shows a warning message saying
*Warning 40042
Plasticity algorithm did not converge for MAT_105 at time....
I had tried inducing initial timestep size qnd even changing the contact parameters from default to SOFT=2 in between the bars and my sample. Still i get the same message.
I would be so nice of you if someone gives me an insight to this problem.
Thankyou in advance
Regards,
