Loads and boundary conditions for plane strain analysis

- [Instructor] In this video,…we're going to set up loads and boundary conditions…for the plane strain analysis.…So let's go and open up the file.…We're going to change to the simulation study tab here,…the plane strain one we set up before.…And just to remind ourselves,…let's go and show the mesh.…Now we're going to constrain the bottom end of the bracket…down here and down here.…

In practice, the loads are going to be carried…in the 3D model by the lower bolts.…But we're going to be focusing on the shoulder region,…so it doesn't really matter that we constrain down here.…The load path, we assume…the stress flow is going to be the same…whether we constrain here…in our 2D plane strain model,…or using bolts in the 3D model.…So as long as we've got that similar load path,…that is quite acceptable.…So let's click on the fixtures icon.…Go for fixed geometry.…And then the two regions we want are this region here…and this region here.…

Now it turns out we also have to…constrain the splits here and here.…Because the way the geometry was set up,…
