Sideplates are a fully bolted construction that reduces/eliminates crack propagation due to stress riser
in the steel caused by welding and provide the ability to quickly replace worn components without cutting.
After the main bearings became loose, the bearing tangs wore and the main bearing in the #2 position started to come apart, allowing the other half of the bearing to move and ride up into the crankshaft radius, creating a stress riser
100" into the rigid section to avoid a potential mechanical stress riser
in the flex portion of the part.
The weakening of the proximal bony support can lead to a stress riser
between the region without bone ingrowth and the distal well-fixed femoral disphysis.
To date, the company has identified three contributing factors - the presence of a stress riser
, differential soil settlement, and excessive stress at the bottom of the pipe.
Additional details using FIB showed that Pd did not form an alloy Pd/Pb with the lead, and secondly, the alloy Pd/Sn that was formed remained segregated in clusters on top of the Ni/Sn alloy, creating a stress riser
In some cases, the marking process left too great an impact on the fabricated steel and challenged the highly critical fine line between an accurate impression and one that created a stress riser
In addition, during thermal cycles any undispersed silicon in aluminum-silicon wire may enlarge and serve as a stress riser
, making the wire prone to crack and fail.
It also provides mechanical stress relief by eliminating a stress riser
of an abrupt pad to trace width change.
Sideplates are fully bolted construction that reduces/eliminates crack propagation due to stress riser
in the steel caused by welding and providing the ability to quickly replace worn components without cutting.
In the submitter's opinion, the failure may have been caused from a stress riser
created during manufacturing.
Inserting a screw into a long bone introduces a stress riser
that can predispose the bone to fracture.
