The investigation of the solutions of the dispersion equation is carried out and all the possible cases of the behaviour of the surface electro-elastic SH wave depending on the electro-mechanical coefficients of the layered structure are revealed.
Student paired t-test was used for the comparison of the calculated mechanical coefficients (P=0.05).
In a previous study, column experiments were carried out with Toyoura sand (permeability 2.05 × 10− 11 m2) and Toyoura sand mixed with bentonite (permeability 9.96 × 10− 13 m2) to obtain the molecular diffusion coefficient, the Knudsen diffusion coefficient, the tortuosity for the molecular diffusion coefficient, and the mechanical dispersion coefficient of soil gas systems.
Finally, mechanical characteristics and coefficients of three Gibson and Ashby analytical equations were also determined, which could be used to estimate the mechanical properties of other SLM fabricated functionally graded lattice structures.
Using this structure, the purpose of this paper is not only to determine the residual stress state, but also the thermo-mechanical properties: coefficient of thermal expansion and thermal conductivity.
The samples were tested for their mechanical properties and the coefficients of thermal conductivity, as well.
The mechanical stresses and the coefficients of linear thermal expansion (CTEs) were investigated by non-ambient (in-situ) X-ray diffraction measurements employing the sin2ψ crystallite group method.
However, the literature showed large standard deviations in the determination of the mechanical properties of the IVD and small coefficients of correlation between mechanical properties and MRI parameters.
In this study, effects of helix angle, mechanical errors, and coefficient of friction on the time-varying tooth-root stress of helical gears has been rigorously investigated based on our previous proposed method.
The elemental composition and microstructure of the coatings were optimized by varying the HMDSN and C2H2 flow rates separately to achieve a combination of excellent adhesion, good mechanical properties, low coefficient of friction (COF) and wear rate.
