Bolt failure mode

Bolt failure mode
The failure form of the bucket teeth is subjected to varying degrees of wear and impact under different working conditions, resulting in varying degrees and forms of failure. The bucket tooth fails after only 3 days of use (approximately 36 hours) under normal working conditions, which does not meet the requirements from both an economic and usage perspective. From the macroscopic photos of the failed parts in this batch, it can be seen that there are obvious furrow like scratches on the front working surface of the bucket teeth, with a small amount of plastic deformation at the tip and no cracks. The front working surface (the surface in contact with the ground) is the thinnest, about 4mm, and the rear working surface is about 8mm.
