I'm doing a little project which came to a stop.
I calculated expected material stress to be ~10 MPa. (bending)
I know that my material (AlMgSi0,5) should carry well that stress, however I'm interested in max allowable stress for this material.
---------------------------------------------------------------------------
Is the formula for max allowable stress correct?:
Sigma_max = R_p0,2 / Ni
Ni = 1,5 (common construction, no safety or health risks)
----------------------------------------------------------------------------
Material properties:
Fatigue failure 140 - 155 MPa
Tensile strength 90 - 300 MPa
Yield strength 65 - 250 MPa
Since English is not my forte, which (if any) of these parameters should I use to determine R_p0,2?
----------------------------------------------------------------------------
Wish you all a happy new year!
Thank you!
