After the surface models, the examination of volume models was started using finite element method. Volume calculation model of lug with boundary conditions and finite elements mesh are shown in Fig. 7. 2D representation of the finite elements mesh (front view) is also given in that figure. Deformed shape model and deformed front view with maximum displacement value are given in Fig. 8. Display of stress field  is given in Fig. 9.
