Hello all!
I am curious. Sometimes I would like to do a trade study on a mechanical component; so in the interest of time, I think I would use 2D analysis techniques so that a) I can save time on the front end in the CAD package and b) save time on the analysis side of things. But I want to improve my limited skills.
Imagine you have a body of revolution. Let's use a simple cylinder with a flange that has a uniform, equally spaced bolt pattern. For example, the image below (from web) which has a 2D cross-section looking (approximately) like the second image. The solid is not truly axisymmetric because of the hole, so I am wondering what kind of techniques, if any, we can use to try to simulate the hole?
Once person suggested that I try to adjust the element properties in the vicinity of where the hole would be in the 2D model. Any thoughts on how to do this or if there are better ways to do this?
Thanks,
KC
