A few comments:
- It looks like you have a fixture at the interface between the outer and inner cylinder. This is not valid, the model should be bound only at the boundary of the outer cylinder and use soft springs to stabilize further.
- Make sure you have applied the temperature to both parts/bodies, not just faces. You will need to turn on "Solid Bodies" filter to be able to select them in the temperature dialog.
- Since the effect you are looking for is "hoop" or radial stress keep this in mind when you are plotting x,y,z stresses.
Thanks for your quick response!
So I adjusted all of the the points you have made, I have attached the results below. I am now seeing a negative value on the inner cylinder but it doesnt translate through the entire model as you can see but when I fix the other side it becomes rigid and goes back to the original result I posted? I can see that if I section the model I get the visual result I am looking for but i need this to be correct across the full model.Any other suggestions?
Thanks for your help
