Caterpillar Exclusive Webinar

Webinars 29 January 2021

Caterpillar Exclusive Webinar: A Review of Fatigue Testing Applications and Resources

TIME: 09.30 US TIME/15.30 UK TIME

Design for fatigue loading and resulting fatigue performance are two key aspects of Caterpillar product design and operation. Caterpillar design and manufacturing teams have access to a range of internal and external resources; at Caterpillar (Joining Advanced Structures, Peoria Technical Centre) and TWI (Cambridge, UK). They provide both knowledge and material/component testing facilities for the wider Caterpillar community.

This webinar will provide an overview of the resources and support available across both organisations, including the topics:

  • Mid-size component fatigue testing
  • Bolted joints
  • How to develop a test programme to understand the fatigue performance of large fabricated structures

These will be covered by a combination of case studies (including related testing/resources) followed by an opportunity for subsequent Q&A and general discussion.

Continuing Professional Development 

TWI awards points towards CPD for delegates attending this webinar. Every hour attendance of a webinar will earn 2 points towards your continuing professional development.

Please contact Becki Parratt if you require a certificate of attendance towards your continuing professional development.  



Carol Johnston - Principal Project Leader – Fatigue Integrity Management

Carol Johnston

Principal Project Leader – Fatigue Integrity Management

Carol joined TWI and the Fatigue Integrity Management section in 2009. She manages a range of projects related to the fatigue strength and structural integrity of welded joints. Her main area of work is on validation fatigue testing of welds using the resonance fatigue testing technique and she is now focussing on how TWI’s experience and expertise can be applied and used in the renewable energy sector.

Xing Sun - Principal Project Leader - Fatigue Integrity Management Section

Xing Sun

Principal Project Leader - Fatigue Integrity Management Section

Xing joined TWI in 2015 as a Senior Project Leader in the Fatigue Integrity Management section. He has experience in designing bespoke fatigue tests, analysing fatigue test data by using both S-N curve and fracture mechanics methods, performing stress analysis using standard strain gauging approaches and FE modelling.

Before joining TWI, Xing worked as a naval architect and structural engineer in an offshore structure consulting company in Singapore for two years. He was responsible for initial and detail design of ship and offshore structures. Xing obtained his MEng and PhD degrees in Naval Architecture and Marine Engineering Department at University of Glasgow and Strathclyde in 2009 and 2013.
