,nCould you try using an augmented Lagrange formulation and try to increase the pin ball radius, so that the contacting area increases. This might reduce the stress concentration. Also, in beam theory the forces are assumed to be acting on the whole cross section which is not the case in reality. As long as you are getting the expected behavior away from the point of loading you should be good.nRegards,nIshan.n
