In my task, I have to analyze the crack propagation in a screw with contact to a screw nut. I didn't find a function in Franc2D that deals with contact elements or contact conditions.
Does anybody know a solution for this purpose?
My XFEM analysis in Abaqus has finally finished successfully. What can I do with the results? I do not have stress intensity factors or J integrals or anything like that. It just offers me phi and...

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
