Reply To: Equivalent stress varying inversely with drop height in explicit dynamics

[Armin]

Thanks Krishna.
I believe what we are seeing in the pictures is essentially stress waves travelling through the frame. Recall that this is a dynamic situation.

I would suggest that you select a point of interest in the model, like a specific location in the frame at or near the impact location, and then plot the eq.stress versus time for an element located in the area of interest. Then compare the results for both drop heights, and hopefully that provides a clearer picture of the results.
