Grinding, improper

Improper grinding of weld seams at corners and sharp edges. 

The method can locate discontinuities open to the surface in porous materials. It is possible to detect porosity, surface cracks and through leaks, which may result from fatigue cracks, shrinkage porosity, cold shuts, grinding and heat-treat cracks, seams, forging laps and bursts as well as improper bonding between joined metals. 

Determination of residual stress of a failed component is one of the most important steps in failure analysis. The determination of residual stress is useful when failed components experience stress concentration, overload, distortion or the formation of cracks in the absence of applied loads, subjected to corrosive environments as in stress corrosion, mechanical or thermal fatigue due to cyclic loading, or when faults in processing such as shot peening, grinding, milling and improper heat treatment such as stress relief, induction hardening, thermal strains, exposure temperature are involved. 

Dental procedures such as forceful extractions can be considered traumatic, and bruxism (teeth grinding) is seen as repeated microtrauma to the TMJ. Muscular imbalance is another etiologic factor that may be a cause of or may be caused by malocclusion. Malocclusion may occur with the loss of a single tooth or several teeth, improper alignment of dentures, and other factors.
