Failure analysis of a nose landing gear fork
TL;DR: In this paper, a detailed analysis of a nose landing gear failure was presented, where it was observed that fatigue cracks developed in the vicinity of the bolted holes, which work as supporting connections, on the topside of the nose fork and, as such, it can be concluded that the referred area was subjected to cyclic stresses originating and propagating cracks in the material.

Multiaxial stress mapping and fatigue failure prediction of aircraft hydraulic pipes
TL;DR: In this article, the complete stress state was found using FEM ‘Frame 3D’ MATLAB® code and analytical stress concentration factors, and the calculated stresses not only mapped well with the fractured patterns of a failed pipe but also correlated to the computational stress analysis performed separately in an FEA software.
