The laboratory synthesis of zeolites is both labor and capital intensive and, therefore alternative methods must be pursued to produce such materials.
One avenue is to use clay materials, such as kaolinite as demonstrated previously to produce LTA [22].

Introduction When the reinforced earth retaining structure in the alternating stress, due to  the occurrence of certain material permanent deformation localized, such as materials  yielding, plastic deformation of reinforced earth and the final fracture of material, which  customarily known as fatigue damage.
When it changes to a certain extent, the materials they will lose the ability to resist fatigue, resulting in fatigue failure.

Based on the analysis and comparison, the statics and dynamics analysis was carried on by analytic method and ANSYS12.1 software,the input stiffness, magnifying multiple and the relationship between output displacement and load are calculated,and the stress analysis shows that the maximum stress of magnifying mechanism is less than the maximum allowable stress of materials.
Selecting the material allowable stress σmax= 980MPa, σmax< [σ].

Introduction As we know, heterogeneous materials such as rock or rocklike material have a composite or heterogeneous microstructure or texture, which can be seen with the naked eye or with a microscope at various magnifications.
Moreover, the behaviour of rock or rocklike materials and the growth of cracks or microcracks in rock or rocklike materials are strongly influenced by this heterogeneous microstructure.
Consequently, the numerical methods used for studying the fracture behaviour of rock or rocklike materials should take the heterogeneity into consideration.
Sum of elastic energy release (ERE) of the all elements is total elastic energy release of brittle materials occurred at current loading step.
