It also has mixed formulation capability for simulating deformations of nearly incompressible elastoplastic materials, and fully incompressible hyperelastic materials.
Then, for real materials with close pitting holes, the analysis of hydrostatic stress gradient should be related to this case, and not to a single pitting hole.

CFG pile means cement fly-ash gravel pile, it is variable strength pile which is made of gravel, stone chips, fly ash, construction waste etc. rejected materials mixed with cement, fine sand and water and which is casted in place by a variety of machines which make pile.
Generally, CFG pile does not need to calculate reinforcement, and can use industrial waste fly ash, slag and stone scraps as admixture materials to reduce the project cost further.
For the main buildings such as matching materials stations, grinding department, cement storeroom, slag powder storeroom workshops etc. which require higher geological bearing capacity we select perfusion pile with post-pressure grouting around pile tip that can have geology bearing capacity changed stronger.

Separate whiskers may appear and grow at 280 o C together with extruded material (Fig.2b), in close vicinity.
Compressive stresses in plastic Cd tend to push up extra material into surface.
As a result Cd occurs under high hydrostatic compression and tends to push up extra material into surface.

The external surface of both electrodes are made of insulating material.
The external surface of the electrodes designed in this paper are made of insulating materials and the signal frequency is in the range of 1MHz~300MHz, so R1 R2 Rs are ignored while in establishing the relationship between sensor output voltage Vo and soil water content θ.
