Crack tip mesh size - Interface cracks ?

Choose a channel featured in the header of iMechanica: 

Hello everybody,

                   I am working on FE Simulation of interface cracks. To this end, I use modified VCCT, CSDEM and other such methods to determine mesh independent strain energy release rate (G) and Mode mixity (ψ). Now I have a fundamental doubt.

Non-linear analysis convergence in ANSYS workbench static structural

Hi,

Please pour in uselful tips & tricks to arrive at convergence in ANSYS workbench static structural. This for Finite Element Analysis in static structural of biomechanical components.

 

Thank You

How to extract angle of twist and shear stress due to torque in Workbench

I set up this model of a shaft with to opposing torque simulating a shaft and pulley system. 

The supports and loads are shown here: Ex-3-9-LoadsAndSupports.png

Note that the origin (top left) has the rotation X constrained to eliminate rigid body motion and to set a reference of zero twist at that point. 

I requested every result that I can imagine, see the Outline here: Ex-3-9-Outline2.png

The torque is shown here: Ex-3-9-TorsionalMoment.png

Are shear-moment diagrams wrong in ANSYS Workbench 16.1 ?

I think I found an ERROR in ANSYS Workbench 16.1 and I hope someone can either CONFIRM or show me what I did wrong. 

This is very important because I am teaching this material, but I do not have support from ANSYS, so I am asking for your help.

I work with both Beam188 elements and

Link180 elements and would like to be joint them together.

Is this even possible, How can I achieve this

how to edit/correction mesh (in ansys workbench)?

Hi 

i want to analysis a model in anasys workbench with modal analysis.but i Encountered to problem.Bad mesh generation (as you see in the below figure) happened that i don know how to solve it,could anyone help me ?

 

Regards,Ali
