Suitable for:

Structural, civil, maintenance, pipeline, materials, welding, inspection and plant engineers including those responsible for maintaining welded equipment and structures, managing the integrity of ageing structures and optimizing asset performance.

Key features of the course:

  • Introduces the concepts of fitness-for-purpose and engineering critical assessment (ECA), using a mixture of lectures, informal discussion, quizzes, videos and software exercises to reinforce learning
  • Focuses on the practical applications of fracture mechanics and covers brittle and ductile fracture, plastic collapse, fatigue crack growth and stress corrosion cracking
  • Highlights fracture and fatigue procedures in BS 7910, with an emphasis on how they are applied to welded structures
  • Discusses the assessment of circumferential flaws in pipeline girth welds
  • Covers a range of relevant subjects related to BS 7910, e.g. failure case studies, non-destructive testing (inspection), materials properties, fracture toughness testing
  • Provides practical training in fracture and fatigue assessments using CrackWISE software
  • Provides engineers with a firm foundation in the application of BS 7910 to the assessment of flaws using fitness-for-purpose methods

Course Content:

Day 1

Failure case studies:
  • Examples of engineering failures
  • Contributing factors and lessons learnt, especially with respect to welded structures

Fitness-for-purpose methods:
  • Concept of fitness-for-purpose methods and engineering critical assessment (ECA)
  • Key factors affecting structural integrity

Fracture mechanics theory:
  • Main principles of fracture (for driving force and fracture toughness): K, CTOD, J
  • Linear elastic and elastic-plastic fracture mechanics (LEFM and EPFM)

Non-destructive testing (inspection):
  • Role of NDT in ECA

Introduction to BS 7910:
  • Background and definitions relating the day's sessions on input data to the terminology (flaw types and stress categorisation)

Day 2

Fracture mechanics testing:
  • Testing (especially welds) including preparation and post-test analysis

Fracture assessment using the Failure Assessment Diagram (FAD) approach:
  • Definition, main parameters, primary and secondary stresses, local and global collapse
  • Main features and input data to FAD assessments

Software Workshop:
  • Fracture assessment to BS 7910

Additional Information:

All venues:
  • This course is given by specialists highly experienced in the development of BS 7910 and in the practical application of fitness-for-purpose methods to a wide range of applications including pressure vessels, pipelines, offshore structures, vehicles, bridges and buildings
  • Training time is typically from 0900-1630, including coffee/tea and lunch breaks, with an earlier finish (approx. 1500) on the final day
  • Participants receive a full set of course notes and a Certificate of Attendance
  • Temporary CrackWISE licenses are provided to participants to allow them to install and use the software immediately before, during and after the training course; participants are therefore requested to bring laptop computers to the course, with the software installed
