FEA Surface Stress x Inside Stress

FEA Surface Stress x Inside Stress

FEA Surface Stress x Inside Stress

(OP)
Hello everyone,

I've performed a FEA in a structure with small radius. The region with radius showed a high stress, higher than yield strenght of material, normally in this situation I just increase the value of radius in order to decrease the stress, above the yield stress then the part can be approved. But I've seen some reports where even thought the surface stress is higher than yield stress the part is approved. They just make a cross section in the region with hight stress and measure the stress 1-2mm into the part. I don't understand why. The surface stress is too hight but the part can be approved just analyzing inside the thickness, as shown below:



Somebody know any theory about this?

Thanks in advance!
Henry.
