Failure Analysis for Engineering Technology StudentsMechanical engineers are often required to perform failure analysis on components that mighthave failed prematurely or unexpectedly. The process is complex and draws upon manydifferent technical areas of mechanical engineering and requires engineers to accurately solveproblems in those technical areas.This paper presents how a failure analysis project is incorporated into a senior-level,undergraduate, material science course and the benefits to the students to employ knowledgegained in other courses to complete the analysis. The project is given as part of a laboratoryexercise on failure analysis. Students are presented with a basic problem definition of a failureand then work in groups of 3 to determine root causes of the failure. A case study of an over 100year-old, 18 ton, steam-powered, steel-wheeled tractor that experienced a boiler explosion thatkilled several people and injured scores of others at a county fairground will be used as anexample.The project requires students to brainstorm, form a hypothesis, problem solve and then presentpossible explanations for why the event occurred. Student performance is assessed by theirappropriate use of strength of materials, heat transfer, thermodynamics, material science(corrosion), and dynamics since all these areas must be employed to solve the problem. Studentsare required to present their hypothesis and analysis to their fellow students in the form of an oralpresentation. As a result of the exercise, students come to appreciate how various elements ofengineering interact to impact the problem.
