[...] This information helps to evaluate whether the assembled parts will remain in place and function as intended in the intended application. If the deformation is too high, design adjustments may be necessary, such as using stiffer materials, adding additional supports, or modifying the geometry of the parts to improve their stability under load. B.3 Safety Factor The third graph shows the distribution of the safety factor in different areas of the assembly, ranging from 1.5 to 3.0. The safety factor is a key indicator of the reliability of the assembly under various load conditions. [...]
[...] Tools and Analysis Techniques The analysis of fretted assemblies relies on the use of advanced tools and techniques such as the finite element method (FEM). The FEM allows for precise modeling of the interactions between the hub and the shaft, taking into account material properties, applied loads, and boundary conditions. This technique provides a detailed understanding of the stresses and deformations within the assemblies, facilitating the optimization of the design to improve performance and durability. II. Finite Element Method for Dimensioning The Finite Element Method (FEM) is a powerful analytical tool that allows for simulating and analyzing stresses and deformations in fretted assemblies. [...]

[...] They define dimensional tolerances, heating temperatures, and compatible materials. For example, the ISO 286 standard specifies dimensional tolerances for mechanical adjustments, while the ASME B4.1 provides guidelines for adjustments and tolerances. These standards ensure that fretted assemblies meet strict quality criteria and minimize the risk of failure. B. Tests and Experimental Studies Many experimental tests have been conducted to understand the behavior of fretted assemblies under various loading and environmental conditions. These tests allow for the characterization of residual stresses, deformations, and the durability of the assemblies. [...]
