Three different types of motion between the journal and bearing can be observed during the dynamics of the revolute joint clearance, namely, (1) free flight mode, in which the journal moves freely within the bearings boundaries, that is, the journal and the bearing joint are not in contact; (2) impact mode, which occurs at the termination of the free flight mode, being impact forces applied to and removed from the system; (3) permanent contact, in which contact is always maintained although the relative penetration depth between the bearing and journal varies along the circumference of the journal [5].
The journal radius of crosshead pin is 35 mm while the initial bearing radius of connecting rod is 35.1 mm.
The materials in contact have the properties of steel with Young’s modulus 2.06×1011 N/m2, Poisson’s ratio 0.3 and zero friction is assumed.
Fig. 5a depicts the journal center path of the joint with clearance.

The data used in this study are academic papers that are published in Science Citation Index (SCI) journals.
Among journals that contained the papers, the top 10 journals in terms of the number of papers were reviewed by the researchers, and the following two journals were selected: ‘Solar Energy Materials & Solar Cells’ and ‘Solar Energy.’
One of the unique details in this study it that both journals the Solar Energy Materials & Solar Cells and Solar Energy that have become the population of research data, showing a great deal of difference in terms of research subjects.
Result of subject classification by text categorization Journal Cell Module/ Array System Relative/ Advanced Total Solar Energy Materials & Solar Cells 1,173 82 21 18 1,294 Solar Energy 104 15 69 549 737 Total 1,277 97 90 567 2,031 It was found that the published number of papers changed in similar patterns in all 4 major subjects as shown in Fig. 2.
It is hound that subject related to Dye-Sensitized Solar Cell material (DSC/DSSC), organic material (PPV), transparent electrode material (ITO) and Polycrystalline Si (which is a common solar cell material) were most active within the major Cell subject.

Both the shrinking and expanding materials exert stresses on the tooth.
Both of these materials are assumed to be homogenous and behave in a linearly elastic way.

Materials property measurement is needed on deformation, fracture and fatigue in hydrogen-containing media.
At the same time, there is a problem in technological support for evaluation of hydrogen compatibility of materials in laboratory conditions for evaluation of hydrogen embrittlement, depending on hydrogen concentration, methods and modes of loading, temperature, pressure and actual properties of materials.
Evaluation of materials for hydrogen pipelines can be carried out in accordance with the accepted provisions of IGC Doc 121/14, ASME B31.12 and ASME BPVC.VIII.3 (article KD-10) standards.
