The constitutive model has the same degree of flexibility when it comes to capturing different soil behavior as existing cone-cap [e.g. 8, 9] or bounding surface models [e.g. 10, 11], but with fewer material parameters and a better mathematical smoothness; rendering it ideal for the simulation of large-strain problems.
Furthermore, its material parameters can be easily determined from conventional laboratory tests, such as triaxial tests.
The model has only 7 material parameters that are all associated with a clear (at least phenomenological) physical meaning, and thus can be directly determined from conventional laboratory tests: 1.

Although Cybersphere system permits operator to walk freely, the sphere has to support the operator and rotate continuously, so its material property is required quite high and it is rather difficult to manufacture.

X-ray photoelectron spectrometry (XPS) is a non-destructive characterization technique and is a very useful tool that allows to identify the elements that exist within a material (elemental composition) or are covering its surface, as well as its chemical state, the general electronic structure and density of electronic states in the material.

In this regard, different formulas of multiple emulsions based on paraffin oil have been developed in order to investigate the effect of hydrophilic surfactants and GX used at different concentrations on the stability and rheology of multiple emulsions prepared. 2 Materials and Methods 2.1 Materials The oil phase used in this study consisted of paraffin oil (U.E SARL PROCHIMA SIGMA, Germany).
After pre-shearing the sample was kept at rest for 600 s prior to measurements in order to permit the material recovering its initial structure partially at least.
