From the creep curves we can also find that when stress difference 31 σσ − remains the same, the confining pressure increases, creep decreases, increasing the life span of the specimen, the creep damage is also a slight increase in the time, indicating the material ductility increases. 2 The establishment of oil shale creep damage model Through testing, oil shale creep is nonlinear and exsists creep flowing in the stage of accelerating creep causing the inner ofrock generating new cracks and in the ever-expanding and resulting in rock strength below its long-term strength because of excessive distortion caused by rock rheology.
When materialω= 0, no damage, when ω= 1, material is fully compromised.

Materials’ parameters Different clays’ parameters are shown in Table.1 Table 1.
But the maximum stress value is less than the theoretic limit of reinforced concrete property, it’s obvious that material property hasn’t been made full use of .Because the von Mises of front wall is larger than of back wall, we think that it is reasonable to give the front wall a larger thickness.

Experimental set-up The material studied is Al 6063 alloy.
The working electrode is the test material.
Generally, it is shown from the polarization curves Fig. 1 and Table 2 that deposition of Cr (Ⅵ) on material surface obviously reduces icorr and shifts Ecorr and Epit towards more positive region as compared to the uncoated substrate.
