Application of modern information technologies to analyze the tensile strength of fasteners

<jats:p>&lt;p&gt;&lt;strong&gt;Context and Relevance&lt;/strong&gt;. he results of using modern information technologies from the initial design stage to the final stage of virtual testing, as well as data on the patterns of processes in the simulated elements and the results of a computational experiment, are practically absent in the scientific literature. Therefore, the development of a systems approach to computer modeling of the strength of fasteners is relevant and has scientific novelty and practical significance. &lt;strong&gt;Objective&lt;/strong&gt;. To develop and test a methodology for computer modeling of the tensile strength of fasteners using modern information technologies. &lt;strong&gt;Methods and Materials&lt;/strong&gt;. The methodology includes creating a 3D model, imposing tensile loads, generating a finite element mesh, and calculating the distribution of stresses and strains. To test the methodology, a standard sample was used, the modeling results of which demonstrated high accuracy and consistency with reference data. &lt;strong&gt;Results&lt;/strong&gt;. A comprehensive methodology for computer modeling of the strength of a stud fastener has been developed and tested using modern information technologies. The developed methodology enables a full cycle of computer analysis&amp;mdash;from constructing a 3D model to determining stresses and strains under tensile loads. The results showed that, based on successful testing, the methodology was applied to a real fastener, with a comparative analysis of the strength properties of Steel 45 and Steel 45G. &lt;strong&gt;Conclusions&lt;/strong&gt;. Using Steel 45G provides a higher safety factor, confirming the effectiveness of the proposed methodology for engineering analysis and optimization of fastener design and material.&lt;/p&gt;</jats:p>
