Welcome Back!

The ability to interact with ASME instructors who bring real world experience, examples, and best practices to life in our learning experiences is a major reason learners choose face to face training. Networking with peers is also a valuable part of the time spent together during a course. We are excited to start offering these important courses again in person.

Schedule: This course commences at 8:30 AM and ends at 5:30 PM local time, each day, with breaks scheduled throughout.

Location: This course will be held at the Hilton Anatole Hotel in Dallas, TX in conjunction with ASME Boiler & Pressure Vessel Code Week. Please follow this link for hotel reservations.

Providing a practical understanding of fatigue and fracture calculations, this course is intended for engineers who are required to perform such calculations, or who specify or evaluate testing and draft fatigue or fracture portions of design requirements. It covers the latest methodologies such as weight functions and the failure assessment diagram (FAD) approach. Related subjects such as damage tolerance analysis, reliability, and risked-based inspection will also be discussed.

By participating in this course, you will learn how to successfully:

Explain the underlying assumptions and limitations of fracture mechanics
Describe the process for material selection for fatigue and fracture resistance
Explain how to perform simple to moderately complex fracture mechanics calculations
Identify codified procedures for flaw evaluation

Who Should Attend
Engineers who work with mechanical design, mechanics and structures as well as those involved in testing and equipment fabrication.

Course Materials (included in purchase of course):
Digital course notes via ASME’s Learning Platform

Supplemental Course Materials (not included with course, purchase separately)
Recommended Textbook, Fracture Mechanics: Fundamentals and Applications, written by Ted L. Anderson (available in eBook and print formats)
