Fourteen vibration fatigue curves of the components and products of the typical materials, processes and structures have been developed.
The S-N curves for many materials can be approximated by straight lines when plotted on a log-log scale, as illustrated for a typical steel alloy in Fig.1 below.
Because material is different, the mode of vibration is different also.

The yield stress of steel C4D was taken from the material database of Forge2011® program and entered onto computer simulation in the form of a function described by the Hansel-Spittel Equation 1 [9, 10, 11, 7].
It is assumed that regarding this model, under abrasive wear conditions, Vz of the material separated from the tool surface of the unit is directly proportional to normal stress, sn, acting on the tool surface and to the friction path, Lt, and inversely proportional to the hardness H of the material undergoing wear (in this case, tool hardness).

In this respect, polyoxometalates (POMs), with versatile structural diversity and unleashing exciting new properties such as high negative charge, represent a widely used inorganic building blocks, have been widely exploited for the construction of organic-inorganic hybrid materials [8-12].
On the other hand, owing to the interesting catalytic, bioinorganic and physical properties (such as mimic functional biological systems and single-molecule magnets (SMMs)), Schiff base and its metal complexes have been extensively used as excellent subunit for the construction of hybird-type materials [13-17].
Given that few works combined POM with metal Schiff base, systematic synthesis of new hybrid materials with these two libraries of interesting and reliable molecular nanostructures remains a pressing challenge [18-21].
Our research, to some extent, provides a new path for the design and synthesis of hybrid materials between metal-Schiff base complexes and simple inorganic salts.

The material cited in the review consists of recent journals and conference papers from academic databases (ScienceDirect, Google scholar, ResearchGate, etc.) as well as from other credible sources such as books and reports.
The work cited broadly covers topics such as ball bearing prognosis, fault size estimation, remaining useful life or residual life predictiction, and fault classification – predominantly journal articles and conference papers from the year 2011 through 2020.
While premature failure of a ball bearing can be attributed to many factors such as corrosion, brinelling, poor lubrication, faulty installation, incorrect design, etc., the main cause is due to material fatigue [16, 17] followed by wear [16] at the running surface.

Though a number of enterprises have introduce and adopt Enterprise Resource Planning (ERP) systems and Materials Resource Planning II (MRP II) systems, the above problem does not be dealt with successfully yet.
The activities corresponding to the production control nodes include production planning and scheduling, processes quality control, materials tracking and path optimal decision, and machining progress and production cost tracking, and so on.
In the production of workshops, materials management and their paths optimal decision plays more important role in reducing the cost and delivery time.

For the optical component, fluorescent dye molecules and QDs are the most predominantly used materials.
These materials were reviewed by Zhang et al. [129].
Due to variable methods, materials and cell lines, the toxicity question is still in disagreement in the published literature.
