i just need someone to paraphrase the whole thing. Thanks

Summary

This set of studies investigated a case of stress and displacement singularity. A cantilever beam, fixed at two points to represent spot welds and receiving a 1000 N load on one face was analyzed. Using 3-D solid elements in h and p adaptive static studies, the stress and displacement results failed to converge and showed unrealistically high values. This indicates that modeling the spot welds as single points created a false restraint condition which allowed singularities to develop. Six additional static studies were performed on 2-D shell
