Model Order Reduction of Bolting and Feasibility Evaluation

The main idea in the present age, is to improve efficiency of computation, by reducing computational space and time eventhough, we have high end computing power. It is still preferred to use minimum computation time and space. We have attempted in this study, to try and reduce a 3D bolt model, to a 2D model, by using the plane stress approach. The objective of the present study is to evaluate the feasibility of reducing the 3D model, into 2D. The requirements of the 2D Bolt, is to match the mass of the actual bolt, and to match the axial and bending stiffness of the actual bolt, and simulate the effects of 3D bolt in 2D, as close as possible to 3D including contact pressures. Symmetry conditions have been used on the cylinder. Elements and meshes have been discussed, and the best technique to simulate the 3D bolt in 2D, has been proposed.
