Reply To: Geopolymer modeling Problem

That's a good plan Maciej. The explicit dynamics solvers should be able to handle this problem. Try applying velocity-based boundary conditions in explicit dynamics (AUTODYN or LS-DYNA) instead of load and then compare the resulting stress-strain curves with those of the experiment. 

If you face any difficulties, you can post it here or start a new forum post and someone will be able to help you.

If you need a good learning resource about the theory of explicit dynamics analysis, checkout out the following lesson: Explicit Dynamics Theory - Ansys Innovation Course - YouTube
