The load-depth curve in Fig. 1
is general raw data from the test, from which various mechanical properties can be obtained.
However, this standard deals only with hardness and elastic modulus, which are insufficient for evaluating mechanical properties.
Generally, tensile properties are considered the most important mechanical properties.
Therefore, in this study we investigated what properties affect the constants and determined their optimum values using finite element analysis.
Due to the small elastic deformation, the elastic property does not affect the plastic constraint factor.

These filaments underwent different characterization techniques to test its mechanical and thermal properties.
The study also covers the testing of the mechanical properties of the developed PLA-MMT composites and compared it with the virgin PLA.
These pellets were then stored in a Ziplock bag and kept in an airtight container with desiccant to prevent any moisture from affecting the materials.
The mechanical properties such as tensile strength, strain at break, and the modulus of rupture are shown in Fig. 4.

Influence of Graphite and Carbon Nanotubes on the Mechanical and Electrical Properties of Cast Epoxy Composites
Clarissa F.
They have excellent electrical insulation and mechanical properties.
In epoxy composites with graphite and carbon nanotube reinforcements, the dispersion of the carbon nanotubes and the interfacial adhesion between the phases, matrix and reinforcement, are important factors that influence the properties of the composite [4, 12].

The Mg-12Gd-2Y-Sm-0.5Zr (wt. %) alloy was prepared by casting technology and the microstructure and mechanical properties of the alloy have been investigated.
High thermal stability and good mechanical properties are crucial for the wider future application of magnesium alloys.
However, the application of the Mg alloys is limited due to their low mechanical properties especially at elevated temperature.
It was found that the Mg-12Gd-2Y-Sm-0.5Zr alloy has excellent mechanical properties and anomalous temperature dependence of tensile strength in the temperature range from 20~300℃.

They
were then tested using conventional mechanical tests at 1070°C/140MPa to determine the effects of
exposure on stress rupture properties.
Introduction Nickel-based single crystal superalloys are predominately used as materials for turbine blades in aero-engines because of their excellent mechanical properties at elevated temperatures.
Microstructure instability of single crystal at elevated temperature during service causing γ' coarsening and formation of topologically close packed (TCP) phases can be a concern for second generation single crystal alloys, since the stress rupture properties can be adversely affected.
The coarsening of the γ' precipitates was observed to be the main factor in the degradation of the stress ruptures properties.

The effect of interlayer on the structure, morphology and mechanical properties of bilayer films were investigated.
The relative fraction of sp3 to sp2 bonding structure in the films is a very important factor affecting these properties mentioned above [4].
The influence of interlayer on structure and mechanical properties of the films is investigated in detail.
These two factors enable the sliding of the grain–matrix interface in Cu/DLC bilayer.

Among all the surface integrity properties, the residual stress profile is the dominating factor that influences the machined workpiece fatigue life [6, 7].
The material mechanical properties are also a strong function of the material microstructure states.
For example, the white layer formation in the machining process is reported to be a strong factor that influences the surface integrity properties [13].
The a phase has much superior material mechanical properties than the b phase.
