Hi sirs,
Don't worry, that is the problem given by the discretization in finite elements method. The analysis result gives always very high level of stresses in front of the load application or the angles of elements. What i use to do : i make the average value from the towo parts of the high value. For exemple if I get 100 MPa in the corner, 20 MPa one meter at right and 35 MPa in left, I make the design with (100+20+35)/3= 55 MPa. Thats takes account of the local plastification and all the special behavior wich cannot be taken in elastic analysis.
Hope it is helpfull
Best regards
