Great tutorial. Thank you!

Hi.
You are welcome.

[@rasoolmokhtarihomami9169]

Very nice. It is perfect.

nice vedio

Thanks, sir, nice video , please make a video for modeling of metal foam in Abaqus

In orthotropic material E in each direction will be different, for calculation the Cd factor=radical(E/density), which E we must substitute E1 or E2?

[@FemexIran]

hi.
actually the formula for calculating the mechanical wave speed for orthotropic materials is not mentioned in the documentation and I don't know how does the Abaqus calculate it.

sir..How to fix flux limit ratio to ensure the stability of numerical simulation by restricting the time incementation?

[@FemexIran]

Hi.
Usually we don't change those parameters of the solver because they affect the simulation accuracy. We try other procedures to get the solution.

Hi sir how to give stepdepth of 0.5 for forming cone shape in abaqus

[@FemexIran]

Hi.
Do you want to do an incremental forming process ?

Please tell me how to adjust the dynamic explicit parameters in ABAQUS to be equivalent to the static loading? Thanks

[@FemexIran]

hi. you must adjust the time period of the step and the mass scaling parameter in a way that the total kinetic energy of the deformable part(s) will be less than 10 percent of their internal energies. this is the main criterion. you can send email to us and explain your problem or question. we will review your needs and give you the cost of answering them.

Sir how to transfer load (concentrated force) from binder (rigid shell) to sheet (shell deformable) in explicit??

[@FemexIran]

hi. I think that contact interaction must be defined between them.
