ANSYS Tutorial - Nonlinear Frictional Contact & Pretension of Bracket Assembly in Workbench 15. This tutorial explains how to use connections, contacts (frictional and bonded contacts), as well as the bolt pretension tool. It shows how to apply two load steps as well as investigate the results using the contact tool.
This tutorial also gives a short explanation on Multizone, hex dominant, mapped face meshing, as well as face sizing mesh controls.
This is for beginners starting in ANSYS.

I would take time to appreciate the way you taught. A must watch video for the ones, who wishes to learn the Static Structural Analysis using Ansys, but can't find it easy to do. This video, takes you through all the basic concepts required for the Analysis and that too without over exaggeration, and by the end of the video, you realise that you have understood it and ready to go!!! Thank you so much Sir. Keep up the good work. 🔥🙏

Also I would love to see how the reliability (time related failures) of a model can be simulated using ANSYS. Eg., If I were to simulate environmental Stress Cracking by putting the part in a humid oven, after how long the weakest member is going to crack. Good job!

@Naveen_Anan 8 жыл бұрын

Very nice videos!!! I have the following questions: 1. Let's say that you have some deform-able bodies and you need to connect through Rigids, How to we do that in ANSYS? 2. Is there any option to transfer the loads, say force or pressure on a surface through a contact surface without physically connecting it or is there any equivalent options. 3. can we plot shear force/ Bending moment diagrams on a 3D models; as in your 1st video on 3D beam.

@drdalyo 8 жыл бұрын

+Naveen Anan you can change the option from deformable to rigid in the Geometry branch in the outline for each body. Yes there is something called Connections to create contact. Moment and shear diagrams are for beam elements only, not for general 3D elements

Here is a tutorial where I use a varying load: kzfaq.info/get/bejne/o6eKfqp_yKqopqc.html To see shear and moment results, you would need to use beam elements, and use the beam results tool. You can also see reaction force results if you change the scoping method

@drdalyo 8 жыл бұрын

+Ufuk Bilgin program controlled will choose the best default method, it wont affect the results in this case. you can do some research on this in the help. (ex. symmetric vs asymmetric), basically symmetric will show you results on both surfaces on the contact, and asymmetric will only show on one surface. asymmetric is usually less solve time.
