Fatigue & Fracture Mechanics Analysis

Monday, November 6th, 2017 | 10am- 6pm | Wichita, KS

Exciting News: Join us in Wichita for all, or some part, of the week of November 6th - 10th. For the first time ever, we are offering five consecutive days of learning with multiple training and a conference. Details about the courses available can be found in the column to the right. 



Background

Fatigue is cited as one of the major causes of in-service failure throughout engineering history. The earliest application of rotating machinery with its attendant cyclic nature produced documented fatigue failures. Early railway axle failures and mining equipment failures prompted fundamental testing and research. The theories on which much of modern fatigue analysis is based on were developed all through the industrial revolution and into the 1920’s.

The advent of more complex structures with more complex loading histories was typified by the introduction of the first jet powered airliners. Sadly, new fatigue lessons had to be learned in the period from 1954 as a result of the DH Comet crashes.

The nature and prediction of fatigue is much more understood today, and is a requirement for most aerospace components. However, the application of fatigue and fracture analysis is not easy. A good background is essential to be able to use the powerful FEA method as a basis for Fatigue and Damage Tolerance Analysis. Much of the terminology used in setting up the fatigue problem through a modern GUI is confusing and the choice of options is not always clear. 

The objective of this short course is to break down the fatigue and fracture analysis process into clearly defined steps, give an overview of the physics involved and show how to successfully implement Fatigue and Damage Tolerance using Finite Element Analysis.

About the Instructor

Tony Abbey - NAFEMS TutorTony Abbey has created and taught a wealth of FEA training  material over the past 20 years. Thousands of engineers across the world have benefited from his live and e-learning based classes. He has developed a reputation for providing the student with an experience that is full of insight gained from his extensive experience, but which also challenges and motivates.Tony has been working with FEA for nearly 40 years, both in Industry and for leading FEA software providers in the UK and the US.

His informal and interactive presentation style allows the key concepts to be taught in a manner which involves participants fully in the course material. Tony presents papers at NAFEMS and other conferences on a regular basis and has been involved with NAFEMS since its formation. He has written a series of very popular articles on FEA for Desktop Engineering magazine.
