Atkins Webinar on Brittle Fracture Prevention

This webinar is intended to introduce various approaches for brittle fracture prevention. It will give a high level overview of various procedures, codes and standards which address brittle fracture. Within this, a description of fracture mechanics-based flaw assessment procedures (eg BS 7910, API 579…) and the various requirements of pressure vessel design codes (PD 5500, ASME) will be included. Typical inputs required for flaw tolerance assessments and their application will be discussed, with a focus on advanced techniques used for reducing inherent pessimisms in the standard procedures.

Yin Jin Janin - Principal Project Leader – Fatigue Integrity Management

Yin Jin Janin

Principal Project Leader – Fatigue Integrity Management

Yin Jin joined TWI in July 2012 as a project leader in Fracture Integrity Management Section. She manages projects that involve testing as well as the applications of ECAs of engineering structures especially those containing non-standard flaw geometry. She is a member of BS 7910n WEE37 main committee and Fracture Panel. She is also Codes and Standards Theme Lead of FESI. As a member of BS and ISO fracture toughness testing committee, she works closely with Henryk Pisarski to lead the development of testing procedures.

Yin Jin's history with TWI dated back to 2008 when she joined the Numerical Modelling and Optimisation Section as a Research Engineer through the Nuclear Engineering Doctorate Programme of University of Manchester. Her EngD work, under the supervision of Prof Stuart Lyon and Prof John Wintle, covered areas of corrosion and materials science, residual stress measurement as well as computational simulation of welds.

Prior to 2008, Yin Jin was a Principal Process Engineer at a foundry in Manchester, leading and developing techniques to improve casting process and product quality. Yin Jin is a Malaysian born Chinese and came from Borneo, Malaysia.
