Many parts fail from fatigue—the repeated cycling of the load, which causes failure even though the calculated stresses are well below a normal allowable stress value such as the yield strength. Instead of designing to an arbitrary factor of safety, you can use your simulation analysis to perform a fatigue analysis. Based on the cyclic loading scenario that you provide, Autodesk Nastran In-CAD software will determine the number of cycles to failure or the damage. This session will discuss the options available for the fatigue analysis, the meaning of the input, and the interpretation of the results. This session features Nastran In-CAD.
- Recognize what type of model is suitable for fatigue analysis
- Learn how to enter the material and manufacturing properties and loading history
- Understand the fatigue results
- Learn how to generate a report that contains the fatigue analysis
John Holtz started performing simulation in 1989, back when it was known as finite element analysis. Over the years and through 3 different employers, he has designed and analyzed furnaces, stacks, and material handling equipment for the steel industry. Such analyses included stress, vibration, heat transfer, and fluid flow (computational fluid dynamics). Holtz also worked for Algor and Autodesk, Inc., doing technical support, writing the user's guide, and designing the software. He is back with Autodesk doing technical support for the Simulation software products. Although computers and software have evolved since he started, the basic principles of simulation have not changed that much. Holtz looks forward to sharing his knowledge of the process with the audience.
