Event description

Description

Presentation Overview

Common failure types such as stress corrosion cracking (SCC), fatigue or overloading may show unusual features that defy expected patterns and behaviours of materials. Some of these anomalies may not affect the outcome however, some may need to be addressed as they may be the reason for abnormal behaviour. One may observe an overloading feature, yet loads applied may be unusually low for such an application/material. Is this really overloading or is there something more to it?

This presentation will cover common failures with uncommon features and how conventional approaches may be misleading, requiring new approaches and techniques to be invented during the investigation. Furthermore, the presentation will show you how to deal with unusual failure patterns and approaches to
determine the root cause.

SPEAKER – Erhan Ulvan, Ph.D, P Eng., FASM

Dr. Erhan Ulvan obtained his BSc and MSc in Metallurgical Engineering at the Middle East Technical University in Ankara, Turkey and PhD. in Materials Engineering at the University of the Witwatersrand in Johannesburg, South Africa. Erhan has broad experience with materials engineering and manufacturing, including: failure analysis of industrial components, metal forming, forging, low and high pressure die casting, heat treatment, metal fabrication, reverse engineering and corrosion control measures. Erhan is qualified by the Ontario Superior Court of Justice as an expert witness. He has extensive knowledge on joining of major alloy types, destructive and non-destructive testing methods, visual examination and codes and standards including ASTM, ASME sections II, VIII and ASME FFS-1.

Dr. Ulvan has been involved in failure analysis and consulting in Metallurgical Engineering aspects since 1983. He has completed numerous failure analysis projects since then. He is the Past President of the Failure Analysis Society of ASM International, Past Chair of Canada Council of ASM International, Past Chair of Ontario Chapter of ASM International, Past Treasurer of Oakville Chapter of Professional Engineers of Ontario (PEO), and board member of CIM Hamilton Branch. He received Prof. Brian Ives Lectureship Award in 2012 and Fellowship of ASM International in 2018. He regularly presents papers related to failure analysis and chairs sessions at international conferences.
