He has published his research papers in International journals and conferences. He is an active SAE Member who has contributed towards Engineering Education activities for students and professional members. He has received several honors and awards to his credit from SAE which includes FISITA Travelling Fellowship by SAE Japan, SAE Ralph Teetor Education Award from SAE International. Mr. S. Shanmugham / WABCO INDIA Ltd, Padi. Mr. S. Shanmugham is a Metallurgical Engineer, completed M.S (By research) and pursuing Doctorate at IIT Madras. He is presently working as a Global Leader –Materials Technology at WABCO INDIA LTD. He has more than 20 years of experience in Failure analysis of metallic and non-metallic materials, surface engineering, accelerated testing, selecting suitable material and surfaceprotection for corrosion resistance, wear reduction and developing new materials technologies. Train engineers in Material selection and corrosion prevention. Major assignments Performed • Detailed metallurgical failure analysis of Automatic slack adjuster and developed, improved material to meet endurance life cycles • Metallurgical failure analysis and suitable remedies for the parts and assemblies failed in the field. • Metallurgical failure analysis of Heavy coil springs in actuator assembly • Development of Concave fillet welding to improve fatigue life of the push rod assembly used in Actuators He is a certified Six Sigma Black Belt. He is an active SAE Member who has contributed to the SAEINDIA Student Member activities. Objectives • Identify potential failure modes for an engineering component and deduce the loading types, material, environmental and structural properties, which govern the onset of failure. • Predict brittle, ductile, fatigue and buckling failure loads for a range of engineering components. • Recognize indicative facets of a failed component from which can be inferred the source of failure. • Understand examination of failed components, suggest likely causes of failure and suggest strategies for testing out the failure mode hypothesis Course Content • Introduction to engineering failure analysis - approaches to failure analysis -General practices and procedure • Failure modes- elastic and plastic deformation, ductile and brittle fratcure, fatigue, creep rupture, wear and corrosion, loading type, material properties, environmental factors and structural properties governing onset of failure. • Tools and techniques in failure analysis - Experimental analysis of failed components-surface inspection, crack inspection techniques. • Case studies of failure analysis from automotive industries On Successful completion of this course, participants should be able to • Analyse engineering failures critically in a given design by considering all possible failure mechanisms (sometimes, these failure mechanisms may be competing with one another). • Understand the significance of mechanical properties of materials and their behavior when influenced by structural, process and environmental considerations. • Obtain greater exposure to the inter-relationship among the material, functional and analytical aspects of the design process. • Use appropriate metallographic/metallurgical methods to determine the type of fracture (brittle, ductile, fatigue), corrosion, wear; and suggest appropriate measures for controlling failure behavior.
