Failure Analysis of Engineering Structures: Methodology and Case Histories
Case 8: Failure of a Tie-Rod in an Aircraft Towing Tractor
A tie rod on a 70-ton aircraft towing tractor failed during a test run, fracturing near a welded bracket that connects to a hydraulic jack. This chapter discusses the failure and the investigation that followed. It presents a close-up view of the fracture surface showing what appears to be a brittle fracture that initiated from a zone of poor-quality weld. It also provides photographic evidence of a weld crack in the heat-affected zone and includes a drawing of a modified weld design that passed subsequent testing.
