It is suitable to describe the nonlinear viscoelastic behavior of materials.
Thus, based on the previous studies, a new damage parameter is introduced into the Burgers rheological model in the unidimensional form: (2) where is the uniaxial strain, A is damage value, and B, C are determined by the materials. ε0 is the threshold of accelerated creep.

He found that the strength improved several times when there existed fiber materials in the earth.
Extension test of the reinforced materials was carried out under different force (see figure 1E).
The testing materials of reinforced earth were prepared by the progress in figure 1A-E.
The degree of compaction of testing materials is 90%, and the moisture content is 6.5%.
The authors would like to acknowledge the junior fellow apprentices for their assistance in preparing the materials.

Several pyrochlore and perovskite materials have shown promising physical and thermal properties for use as complementary upper layer of YSZ in the FGM TBC system.
These materials exhibit lower thermal conductivity and higher thermal stability than YSZ [2,5,6].
To remedy this shortcoming, the candidate materials were tried as complementary topcoat for YSZ in double layer systems.
