Hello,
I’m pretty new to Creo and Creo Simulate, and I’m using Creo Simulate to look at the stress distribution in a bimetal rectangular beam.
The bottom half of the beam is aluminum, and the top half is steel. The halves are bonded together. The entire beam is heated from 20 degrees C to 200 degrees C. The left side of the beam is fixed in the X direction.
This results window shows the XX stress in the beam. The green regions are negative (compression) and the yellow regions are positive (tension).
Front view of beam:
if you start at the left and move along the x axis, the stress distribution looks fairly uniform until you get to the end of the beam, where it changes a bit.
If you rotate the beam to look at its right side:
Here the stress distribution looks “blotchy.”
Should I expect the stress in the beam to be uniform throughout? Or is it normal that the stress gets complicated at the end of the beam, on the right side?
Thank you!
Steven
