Fracture Toughness Testing

Seminars 30-31 October 2019

Fracture Toughness Testing

Is it for me? 

Anyone involved in carrying out, analysing or specifying fracture toughness tests. Relevant to test technicians, engineers, metallurgists and researchers.

What will I learn?

Background to fracture mechanics testing, and introducing common National and International standards (BSI, ASTM and ISO). This extends to selection and production of fracture mechanics test specimens (including CTs, SENBs and SENTs), and the procedure and instrumentation for carrying out the test (both single point toughness and tearing resistance curves). The sessions conclude with a discussion on how to report the test results, and outlines common pitfalls. You will also be shown around the fracture testing facilities at TWI.

What will I leave with?

By the end of the course you should be able to:

  • Understand the different types of fracture toughness test standards and specimens, and when each might be preferred
  • Appreciate what is involved when generating tearing resistance curves, or when post-test metallography is required
  • Ensure that full details are specified when requesting tests, and reporting the results
  • Appreciate of the range of fracture testing and services that TWI can offer

Meet the team

Phillipa Moore - R&D Manager, Materials

Phillipa Moore

R&D Manager, Materials

I currently work in the MPF section as the R&D manager, applying the blend of my structural integrity knowledge and metallurgy background to identifying new areas to explore, particularly within environmental testing. For 3 years I was the Team Manager for Fracture Testing and Materials Characterisation within the AFM group at TWI, responsible for fracture testing strategy. In the past I have managed projects over the years on fracture toughness testing, ECA and failure investigation.

With a metallurgy background and as a qualified Welding Engineer within Structural Integrity I bring a breadth of knowledge and experience to the projects I manage. My specialism, if I have one, is within fracture toughness testing and its standardisation, and application of these methods to specialised test conditions.

Matthew Haslett - Principal Project Leader

Matthew Haslett

Principal Project Leader

Matthew joined TWI in 2012. He read Mechanical Engineering (MEng) at the University of Cambridge (Churchill College) and has prior work experience in Nuclear Engineering, the Armed Forces (Royal Navy) and the MOD. He is currently a Principal Project Leader in Asset and Fracture Integrity Management (AFM) and a Chartered Engineer (IMechE).

Matthew’s main areas of expertise lie in fracture toughness testing, general mechanical testing (both standard and bespoke) and Engineering Critical Assessment. He also co-ordinates mechanical testing on behalf of AFM, lectures on a number of TWI training courses and mentors colleagues working towards Chartership. He is currently the Chairman of The Welding Institute Younger Members Committee, with a particular interest in education outreach.

Part of Matthew's role as Chair of the Younger Members' Committee of The Welding Institute is to organise education outreach events in the local community. This ranges from Welding with Chocolate workshops at local primary schools, to site visits and careers talks for sixth form students and undergraduate engineers and scientists.

Talking about this part of the role, Matthew says "The importance of education outreach cannot be underestimated. The STEM professions are crying out for good quality scientists and engineers and it is vital that children are shown, at an early age, the fantastic opportunities that are out there for them in their future careers".
