The mechanical responses of granular materials are affected significantly by the properties of the individual particle.
The mechanical properties of granular materials are affected significantly by the particle shape, surface characteristc of the individual particle and consolidation stress of the assembly.
Therefore, it’s vital to establish the link of macromechanical properties to fabrics, which has attracted more and more attention recently[1][6].
The friction angle can be computed by the relationship between friction factor and friction angle (Scott 1963)
Influence of micro parameters of sandy soil on its macro properties.

The objective of this work is in order to investigate how the mechanical properties of bioplastics synthesized from chitosan and porang starch with sorbitol plasticizer are affected by varying drying temperatures.
According to the study's findings, changes in drying temperatures significantly affect the mechanical properties of these bioplastics.
Drying temperature and time are crucial factors in determining the quality of the plastic, resulting in elastic and durable packaging [14].
For all the factors under analysis, the ideal circumstances are produced by a blend of drying time and temperature [15].

The effect of deposition temperature on microstructure and mechanical properties of ZrN coatings fabricated by DC magnetron sputtering was investigated.
Introduction Hard coatings are used to enhance the mechanical properties of materials surfaces.
Different deposition techniques and processing parameters would vary the microstructure and mechanical properties of ZrN coating [5].
The aim of this work is to investigate the procedure for ZrN coatings growth and the effect of Ts on the structure and mechanical properties of ZrN coatings.
The hardness slightly varies may be due to the difference of some factors such as preferred orientation, grain size, residual stress and consistence.

Sintering parameters are undoubtedly among the many factors that influence the mechanical properties and hydrothermal ageing resistance of tetragonal zirconia ceramics.
It is during the heating stage that grain size increases continuously causing an adverse effect to the mechanical properties of sintered zirconia.
The decrease in hardness of the 3Y-TZP samples sintered above 1400oC could be mainly due to two factors.
