- Abstract
Students attending ASM Materials Education Foundation camps are taught about and engage in various materials science and engineering concepts—including failure analysis. As part of the weeklong camp, high school students perform failure analysis on actual fractured components and present their results at the end of the camp. In this case, the students of one group were tasked with determining the failure of a commercial bed frame, which had developed visible cracks during use over 1 year. This paper will detail their results, obtained by performing optical and electron microscopy, as well as chemical and mechanical testing. Their analysis determined that poor welding design and weld practices led to fatigue cracking that would have caused a through fracture of the posts upon further use.
