Bolt bearing failure

WebIn the simplified analysis, the following failure modes are considered: Tension failure across the net section; Shear failure along two planes; Bearing failure; A factor of safety is calculated for each of the failure modes, and as long as each factor of safety is acceptable then the lug can be considered to pass. The figure below shows the lug ... Web1. Hydrogen Embrittlement. This is a very serious type of failure that can take place when a bolt breaks off and projects like a rocket due to the high load on it.
