I am designing a small powdered metal part for the automotive market and I am not sure what failure criteria I should use for the FEA. The part will see a significant bolt up load but very little dynamic load. Elongation at fracture of this material is about 4%. Should I consider it a failure...
I have a belt-pulley problem that I could use some help with. The purpose of the FEA is to determine operating stresses in a new pulley design. The pulley will use a multi-V belt but I am only concerned with stresses close to the center of the pulley so the belt grooves do not need to be...
You will need to consider vehicle G levels (pot holes, etc...),engine vibration, and thermal expansion. Most of the exhaust failures I have seem were due to thermal expansion. Good luck.
Hello all,
I want to make some design changes to a bracket attached to an IC engine and I want to make sure I end up with a part as robust as the one it is replacing. Tooling is expensive so I would like to validate the bracket using FEA techniques before actually ordering parts. I have...
I would agree that Mechanica is aimed at designers more than engineers. Mechanica is relatively easy to use but way oversimplified. I haven't used the wildfire version yet, but meshing was transparent in the previous versions which is a major drawback. The program will freeze during meshing or...
Mechanica assumes contacting parts are welded unless otherwise specified. I think this would work for a bolted joint if you analyze the bolt loads based on your FEA results to make sure you haven't exceeded the sheer or tensile strength of your bolts.
