The Structural Integrity Course was held 4 times- January 2016 (2 Sessions), March 2017 (1 Session) and December 2017(1 Session). In each session the course has been well attended by delegates from across Europe with excellent feedback. Delegates were keen to participate and completed the course satisfactorily. Contact us in case you want to save a place for the next session of the course.


The Structural Integrity Course offers a comprehensive programme to cover the main aspects of the assessment of engineering structures and components under the effect of mechanical loading, high temperature and harsh environments containing cracks. The course provides delegates with the knowledge and skills necessary to engage in structural integrity assessment cases involving failure mechanisms as fatigue, fracture, corrosion, creep and their interaction. The course will first review key theoretical aspects for the delegates to understand or refresh key concepts, and will then make focus on practical issues of structural integrity assessment.

Course Content

The Structural Integrity Course
The subjects given during the duration of the course (see below), will provide delegates with tools to:
  1. Get sufficient theoretical background to gain confidence in the use of typical Fitness For Service assessment procedures and understand their limitations.
  2. Use engineering criteria and simple approaches to make predictions of life and threshold conditions and demonstrate the structural integrity of an in-service component containing defects.
  3. Include different mechanisms ( e.g. fracture at high/low temperatures, aggressive environments, etc.) in the analysis in order to predict their contributions to crack tip loading as well as their influence on material behaviour.
Fracture Mechanics & Fatigue (Dr. N. Larrosa)
- Introduction of the failure of structures and machines.
- Crack tip mechanics.
- Intro & application of Linear Elastic Fracture Mechanics.
- Fracture mechanisms in engineering materials.
- Plastic collapse as a failure mechanism.

- Structural assessment: Assessment based on the Failure Assessment Diagram (FAD)*.
- Comparison & Discussion of solutions of Fitness-for-service standard codes (API 579-1, R6, BS7910)
- Numerical Modelling: Stress/strain modelling and assessment of fracture parameters*.
- Case studies .
*ABAQUS finite element software (Dassault Systems) and Crackwise fracture mechanics software (see will be used for solving practical problems. There is no requirement for delegates to have any previous experience with these software. Assignments will be tailored to the delegate previous experience. Attendees should download ABAQUS for free on their personal laptops from the SIMULIA Learning Community or DS Academy webpages ( or Crackwise licences will be provided to attendees a week before the start of the course.
