The high value of Young’s modulus and the relatively low mass density permit 3C-SiC to achieve higher resonant frequencies compared to other materials.
Cubic Silicon Carbide with its larger E/ρ (where E is the Young’s modulus and ρ is the material density), yields devices that, for a given geometry, operate at significantly higher frequencies than otherwise possible using conventional materials.
This result is consistent with what was observed in other materials like silicon, where defects can reduce the Young’s modulus value.

This opens a wide field of applications for composite materials and nanomaterials.
These particles may comprise metal or non-metallic materials, organic or inorganic, solid or liquid.
All types of condensed substances, liquids, solutions, polymeric materials, glass, ceramics, ionic compounds and metals or gels may theoretically be used as raw materials in the production of nanofibers (Sodomka, L. 2009).
The use of nanotextiles in the construction and preservation of cultural heritage as carriers of properties to the materials to which they are applied, such as the ability to locally reinforce the damaged historical materials, or to provide resistance to the harmful effects of an aggressive environment, etc., is a promising direction in the development of these materials.

The material behavior of AHSS show unpredictable and sudden fracture during sheet metal forming process.
The anisotropy effect, in sheet metal forming, should be considered to assess the material behavior accurately.

This work considers the possibilities of using static analysis and scanning electron microscopy techniques to determine the properties of disperse materials, i.e. corrosion resistant steel grades 12H18N9T (AISI 321) and 20H13 (AISI 420), taken into account in the selective laser melting technique.
One of the important tasks, and in many cases, the most important one, is to develop technical requirements for the powder materials employed in selective melting using electronic and laser radiation.
The dispersion (grain size) for powder materials PR20H13 and PR12H18N9T were determined using a Occhio500nano image analyzer manufactured by Occhio SA (Belgium) using the static image analysis technique in accordance with ISO 13322-1:2014 as shown in Fig. 1.

Meanwhile, this constitutive relation also suits for kinematic hardening material and elastic-perfectly plastic material.
In stress space, material is at strain harding stage, when stress increment directs to external loading surface, it would produce an elasto-plastic strain increment.
Building heat-elasto-plastic constitutive relation of materials has already become research topic which academia concerned about.
