Study the effect of changing the different engineering parameters on the performance of the joints used in the metal structures to find their optimal designs by CAD

This article presents a study of the method of Finite Element Method using the CATIA V5 program to study the effect of various engineering parameters on the best performance of the joints used in metal structures. The proposed model adopts bolt fixation and takes into account the type of material, nonlinear geometry, initial deformation, friction between adjacent surfaces and pre-tensile force in screws. Using the finite element method we will study the best performance by changing the radius, the thickness of the final plate, the length of the supporting column and the angle of the supporting nerve. Results of failure patterns, resistance change, initial smoothness and rotation capacity were presented. Overall, the best performance of the metal joints of a screw-mounted plate was discussed in detail and recommendations were made for the design process
