Because of the need for bolt and nut joints, the tensile strength of the bolt is measured using DTI washers. This kind of gaskets has bumps and troughs on their surface, which is determined by squeezing them to a specified value, the precursor force of the bolt. In this study, the simulation of the performance of DTI gaskets with standard and standard results was used to investigate the dimensional dimension and the material of these type of gaskets under axial loading. Comparison of the results of the displacement and displacement diagrams and the method of removing the DTI gasket in the experimental and numerical model indicates the acceptable conformance of the model is presentedThe simulation process is performed with finite element software, in which the nonlinear effects of matter, contact, and deformation are considered. The parameters studied in this study include height, width, length, radius and bulb angle, thickness of the gasket sheet, radius of the protrusion position and hardness of the material. The results of this research are used in the development and development of DTI gaskets for use in construction bolts and nuts in the interior.
