TMF tests were performed in both IP and OP for varying mechanical strain ranges in the [001] crystallographic direction until TMF crack initiation was obtained.
Introduction In the hot sections of gas turbines the components are often made of single-crystal nickel-base superalloys to withstand the high temperatures while still maintaining good mechanical properties, thus achieving a good efficiency of the gas turbine and in turn reducing pollution [1, 2].
Five test specimens were tested at different mechanical strain ranges (∆εmech), two in both IP and OP loading and the last one in only IP loading, where an extensometer with gauge length of 12.5 mm was used.
where Gr is the slip resistance on the plane, and has the same value for all slip systems, and the following macroscopic equivalent stresses were employed σαe = � �ταpb� � + κ1 |ταcb| + κ2 |ταsb| + κ3ταpe + κ4ταse + κ5σαpn (3) where the first shear stress ταpb is the Schmid stress and the following five are non-Schmid stresses, and the κ1 through κ5 are weight factors that describe how the non-Schmid stresses affect the yield limit.
The weight factors and Gr are temperature dependent parameters, which are determined from experimentally obtained yield data.

Tension force is an important factor to affect the motion of mooring system in deployment．According to the space discrete model，the tension force between node and node can be determined by the relative distance between adjacent nodes and stiffness of cable.
The unilateral boundary condition at the sea floor is modeled as an elastic foundation with linear stiffness and damping properties.
The impact force is defined as the displacement, velocity between anchor and seafloor, and the properties of sea soil.

Adding elements like Zn, Nd, Ce, Gd, Zr, and Ca can significantly enhance these alloys' mechanical and biological properties [46, 47].
It indicates a promising direction for further research into the biomedical applications of these materials, emphasizing their potential in medical implants and devices where biocompatibility and durability are critical factors.
During the comparison of Nd and Ce, no process affecting a genetic disorder at the chromosomal level was observed in any sample.

In the study here proposed, the property of the welding plane was highlighted for an industrial component that was cut through a profile cross section carrying out both metallurgical and mechanical investigations.
As far as mechanical tests are regarded, micro-hardness tests were executed nearby the welding line; in this way, correlations between material metallurgical evolutions and subsequent local mechanical performances were highlighted.
Anyway, die shape is just one of the variables that strongly affects the welding strength of the joint lines; in fact, many other parameters have to be considered, too, like: extrusion ratio, portholes number, extrusion speed, bearing length and billet temperature [5].
The friction forces were predicted through the shear model; more in detail, according to the die element-material interface friction factors in a range between 0.7-0.8 were used [5,13].

Factors affecting the film preparation were controlled to be applicable for actual production and market improvement.

Different types of properties are assigned to these instances.
In fact these properties are assigned to the instances mother classes therefore these instances inherit assigned properties eventually.
These properties are called “Data properties” in ontology model.
Developed ontology model is including hundreds of classes, properties, and relations.
Wire deflection, discharge gap variation and lateral vibration of the wire are the main factors influencing KERF [4].

Venugopal et al. [3] used the Taguchi method to discuss the effects of punch die angle, expansion ratio and friction conditions and found the most significant factor affecting the finished product is the punch die angle.

The forming is conducted at room temperature and lubrication oil is used at the interface of the tube and dies, therefore, a constant shear friction factor of m=0.12 is adopted in the FE simulations.

One of the key factors in the development of high-performance ESC systems lies on the properties of its active electrode material and the electrolyte.
These promising properties of ILs can be linked back to their unique structures that are formed by weak interactions of large cations and charge-delocalized anions [1, 8].
To address these challenges, intensive exploration on the selection of IL composition and properties has been carried out in various literatures [14-16].
Another effort in enhancing the mechanical and electrochemical properties of IL-based electrolytes was demonstrated by tethering ILs to titania nanoparticles to produce a solid electrolyte.
Surface tension is a physical phenomenon brought about by the cohesive forces between liquid molecules and is considered as one of the important properties that may affect the electrochemical performance of an electrolyte system.

It makes sense to expand the area of using the unique properties of these materials in mechanical engineering, particularly, in the manufacture of welded metal structures.
This is due to the peculiarities of its physicochemical properties [18, 20].
Investigation of the Technological Properties of the Protective Coating The behavior of the protection coat at heating was investigated using an OD-103 derivatograph, and the end products of pyrolysis were studied on a GACH-21.3 chromatograph.
The use of the developed protection coat allows to increase the efficiency of the open arc welding, to improve the surface quality and to ensure the preservation of the metallic structures specified mechanical properties, to eliminate the formation of local stress concentrators in the surface layer and, thereby, to eliminate the need to introduce additional technological operations for cleaning and grinding the surface.

Inhabitation and locomotion of animals are major factors that lead to biodegradation and biodeterioration at the cultural heritage sites.
Introduction Cultural relics and architecture monuments, especially those in the list of the world cultural heritage sites, are regarded as one of the common properties for all human beings.
Passage of time (inherent susceptibility; change of taste, function, and architecture), disasters (earthquake, fire, flood, war), climatic changes (temperature, humidity, rain or other precipitation, and sun exposure), human aggression (iconoclasm, vandalism, theft, tourism), and biological activity (growth and metablism of organisms) are token as primary factors that cause irreversible damage to the work of art [2,3].
Up to now, few study was aimed to analyze stress and load carrying capability of cultural properties when animals live on it, the relationship between animal's locomotion and cultural relics preservation is still undefined.
The motion properties of geckos have been well studied [14,15].
