| Abstract | New engineers in mechanical design occasionally encounter difficulty when forecasting the fatigue life of created parts under dynamic conditions. This is because, during the design phase, the size of the pieces is regularly adjusted along with the changing material type, the modified design factor, and even the magnitude of the load in order to generate a prototype that is most compatible with the design circumstances. However, theoretically estimating a part's fatigue life is challenging and time-consuming. Therefore, It might not be the ideal option for the current mechanical design process because it contradicts the QCD paradigm, which is thought to be the cornerstone of industrial production. As a result, this article presents a graphical technique using AutoCAD software to estimate the fatigue life of test specimens made of ferrous metals with ultimate tensile strengths ranging from 490 to 1400 MPa. This approach produces accurate and reliable results when compared to an equation-based fatigue life estimation procedure. This method shortens the time and expense of design. Additionally, as compared to the conventional way, increases the mechanical design's flexibility and agility. |
