The submodels cut the global model along lines that are diagonal to the global model's regular geometry. The static analysis procedure is used. Problem descriptionModel:The global model dimensions are 8.0 × 1.5 in the r–z plane. Material:
Step I boundary conditionsAlong the left face of the model =0. One node is further constrained so that =0. Step I loadingIn all models a pressure of −1.0 × 106 is applied to the right-hand face. (A figure with the same geometry and loading is shown in Two-dimensional continuum stress/displacement submodeling, except with rectangular Cartesian coordinate axes x and y instead of the cylindrical coordinate axes r and z.) Step II boundary conditionsThe bottom face is constrained in all degrees of freedom. Step II loadingIn all models a twist of 0.01 radians is applied to the top face. Results and discussionIn all cases the nodal displacements for the driven nodes in the submodels are correctly interpolated from the global model results. In the cases presented, element and nodal responses in the submodels match the responses in the global models. Input files
