Fracture Mechanics for Pipeline Engineers
Led by Dr. Ted Anderson
May 22-23, 2018: Houston

Day 1
  7:30am Registration & coffee
  8:00am-5:00pm Course
Day 2
  8:00am-5:00pm Course


This two-day course is ideal for engineers who work in the pipeline industry and are faced with the technical and regulatory challenges associated with the seam weld crack threat. The instructor is Dr. Ted Anderson, who is a well-known expert in fracture mechanics with many years of experience in the oil & gas industry.  The attendees will receive a grounding in fundamental concepts of fracture mechanics, but with a focus on practical applications of this technology to the pipeline crack threat.

A laptop is required for this course.


  • PDF files containing all presentation slides.
  • Textbook: Fracture Mechanics: Fundamentals and Applications, 4th Edition (2017), by T.L. Anderson.
  • An Excel-VBA application that performs burst pressure calculations, rainflow analysis, and pressure cycle fatigue analysis.

Who should attend

  • Pipeline engineers
  • Designers and service professionals who are involved with the maintenance, inspection, and repair of pipelines.

Continuing Education Units

Upon completion of the course, participants will be eligible to receive1.4 CEUs.


Dr. Ted Anderson is the author of a best-selling book on fracture mechanics, which has been adopted as a required text in over 150 universities. He recently returned to independent consulting after serving as Senior VP of Technology Development for Team Inc. and the Chief Technology Officer for Quest Integrity. He founded a consulting and software company in 1995, which was acquired by Quest Integrity in 2007. He holds a Ph.D. in Metallurgy from the Colorado School of Mines.
