It can be seen that R1 is defined on the basis of the assumption that rock material behaves with Mohr-Coulomb's criterion.
Then Rock material is in the failure state when 1=ω , and in the relatively safest state when 0=ω . 3.

The pile is considered as no-porous elastic material with a length of 15m and a diameter of 0.4m.
Both the 5m high embankment fill and the 15m thick soft soils were considered as Mohr-Coulomb materials and all of the material parameters are listed in Table 1.

These materials have found wide application in high temperature electrode, solid-oxide fuel, batteries, oxygen sensors, oxygen pumps and oxygen-permeable membranes catalysts [5].
Appropriate amount of starting materials of Sr(NO3)2, Co(NO3)2×6H2O and Fe(NO3)3×9H2O were dissolved in ethanol, then the citric acid solution were slowly added to them(n(COOH-)/n(NO3-)=0.64).

The development of computational FE software based on CDM is important for creep damage to predict the ultimate strength and mechanical properties of engineering materials under a variety of conditions [23].
Hayhurst, et al DAMAGE XX is 2-D CDM-based FE solver, which incorporates the physics of the creep deformation and rupture of individual phases of the weld materials [14].
It includes both the elastic and plastic analysis of materials incorporating damage effects [15].

Raw materials and experiments Raw materials An ordinary Portland cement (CEM 42.5R) was used.
When the raw materials and water were completely mixed, the cement pastes were immediately placed on the magnetic stirrer at 25°C.
