The time Fatigue Analysis with the Ansys Mechanical Software Fatigue Tool The course will give you the skills needed to improve your engineering designs and to increase their reliability. The following fatigue-evaluation topics describe each step in detail and provide additional information: 5. Fatigue is the phenomenon in which a repetitively loaded structure fractures at a load level less than its ultimate static strength. Fatigue analysis is crucial in ensuring the durability and reliability of mechanical parts, especially those used in automotive, aerospace, and civil engineering applications. Interpret S-N curves and strain-life parameters for material behavior. Because of this, fatigue analysis is today often a well-integrated part of the product development cycle. The loading is described as a Power Spectral Density (PSD), and the fatigue analysis mimics a test sequence employing an electrodynamic shaker. However, you can modify scoping and apply it to individual parts or faces as desired. Enter POST1 and Resume Your Database 5. Recognize the most important component concepts of computational fatigue analysis, including the handling of mean stresses, techniques for cycle counting and damage accumulation, and the effect of surface conditions. Following completion of this course, you will be able to: Understand fatigue concepts, including crack initiation and growth. This tutorial will guide you through the fundamental concepts, setup procedures, and best practices for using the Ansys Fatigue Tool effectively. By default, the results are scoped to All Bodies. . This follow-up article deals with fatigue calculation types and ways of displaying results available in the ANSYS Fatigue Module. For instance, a steel bar might successfully resist a single static application of a 300 kN tensile load, but might fail after 1,000,000 repetitions of a 200 kN load. 5.
