Dear Dennis,

I have allowed your request for google drive access.

Your suspicion about incorrect values ​​of constants for the material model used is unlikely, since I have performed several test simulations using these constants and the results of the numerical simulations coincided well with the results of the natural experiments.

Thank you very much for your link to the video.


Additionally, I would like to ask another questions regarding the output of calculation results after the explicit solver has started to be used:

switching from implicit set this curve, from time 1 second

 

I set the curve for output 8

but in the process of solving it, I receive the following information:

 

Despite the messages about solving the problem using an explicit solver, the recording of calculation results after 1 second does not occur.

I cannot understand
- Why does the information output occur with an interval of (approximately) 0.0009 seconds,
if I ordered the output with a much smaller step – 1E-5 seconds – see curve 8

Based on the recorded calculation results, it can be assumed that
at the stage of using the explicit solver, LS-DYNA records the results according to curve 8,
and after starting to use the explicit solver, LS-DYNA does not record the results according to curve 8
