Bolt Modeling in ANSYS—Method 1

Published by:

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).

Multiple Ways to change Material Properties in ANSYS

Published by:

Hello All,

In this post, I am going to show couple of methods to change the material. In ANSYS, material properties like Young’s Modulus, Poisson’s Ratio for a particular material are available under Engineering Data. You can add these materials to the project.  I used the same example project from the structural analysis of a plate.

In the following video, I have shown the following:

  • How to add material to the project
  • How to duplicate a material and edit the material properties
  • How to change material properties inside Mechanical using APDL commands. This method is useful especially if you are lazy enough to go back to workbench project page, add material or duplicate material to edit the material and then update the project to get the material added to the model. Using this method, you can avoid all that and directly edit the material property on the fly. Should be used only for quick checking. Otherwise you may forget the command snippet and wonder about the results.
