Currently I am analysing Brake Flange component , Here there are 4 Bolts which acting 106206 N -total. I need to analyse whether is it safe or not.
I did 2 iteration for ductile material - 350 Mpa Yield Strength.
1. The Von-Mises Value is 840 Mpa & Principle Stress P3 - 192 Mpa ( Due to compressive Load ),
Here Von Mises value is not within the limit of yield strength, but P3 value is in limit. In this condition I consider von mises value
So this is not in safe. In Practical this gets crack , so analysed value is right.
2. I changed the design and analysed the flange for same material.
Now Von Mises Value - 470 Mpa & P3 - 178 Mpa
Here Von Mises value is not within the limit of yield strength, but P3 Value is in limit. In this condition I said von - mises value .
So this is not in safe. In Practical this is OK.
Kindly give the solution for this model.
Give difference between Von-Mises, Principal Stress P1, P2, & P3
