I'm moddeling a steel-timber connection (single shear static test) using ea dynamic explict analysis in abaqus.
Innitially i've tried to model the conenction using a static solver, but at some point the model do not converge - i think the problem is somehow related with the interaction between the surfaces - i've modelled it considering a surface-to-surface contact.
Regarding the dynamic model, it was the alternative for the non-converging static model.
Notice: I've used a constraint of the type "coupling" in the base of the timber and 1 support (Ux=Uy=Uz=0) at the control point to obtain the reaction force. The displacement was applied in the oposite side of the steel plate.
In the dynamic model, althougth the simulation is running until the end, the reaction force is not as expected. I've noticed that it changes if i consider different mass densities for the material. What strategies can i use to obtain the "real/correct" reaction force (or in other words, the load-dispacmente curve) as in a static test? Mass scalling? I've been trying that way, but the problem remains...may be i'm not using the rigth parameters...
Does anyonne has an ideia why either the static and dynamic models are not running as expected?
The contents of the image you uploaded indicate that the model isn't challenging to simulate using the static general modeling solver algorithm in ABAQUS. However, you've chosen to utilize the ABAQUS Explicit solver. What's the reason behind this choice? The spikes observed in the graph are a consequence of the explicit solver and its handling of mass. Have you made any adjustments to the mass scaling parameters? Connect with me for further discussion on Https://wa.me/+923440907874
P. A. Salvattore that should not be an issue for convergance, however, yes, mass scalling will help you in that regard.
