Bolt Modeling in ANSYS—Method 1

Hello All,

It’s been a long time since I have posted a tutorial. I have lot of topics ready for this blog but it is difficult to find apt models to suit the blog’s purpose of making the tutorials as practical as possible.

In this post, I have chosen a simple model for extracting shear loads for the bolts. Bolt modeling using line elements is explained. There are at least 5-6 other methods where you can model the bolts differently. Here is the link for the blog which explains in detail about the bolt modeling methods:

An Overview of Methods for Modelling Bolts in ANSYS

Line method is generally used for global analysis. By global analysis, I mean that all the components of the assembly are modeled and analyzed using a single analysis. This method is a conservative approach where large safety margins are common. Pretension is not included in this method. Note: In this video, beam elements are directly connected to the shell elements with a single node-to-node connection. In general, care should be taken to distribute the load to the nodes around the beam element (which is usually the size of the washer area).

 

Thanks for reading the post!!
