I'm doing a little project which came to a stop.(adsbygoogle = window.adsbygoogle || []).push({});

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!
