Finally, contrast to the stress-strain curves of the model in Figure 3, it can be found that many stress-strain curves of engineering materials are similar to it.
(4)Many stress-strain curves of engineering materials are similar to the model, so the elastic energy change rate method has a certain universality, and a very important practical meaning in engineering.

A meso-damage model is proposed, which include the damage law under complex stress state for brittle materials, and the damage evolution based on stiffness degradation.
With the same idea, Chen Y Q(2002) simulated the fracture course of 3-D sample of brittle materials.
For the brittle materials of rock like, the damage mechanism of tension strain is appropriate, namely the meso-MSS is tensile fractured.

The corrosion caused or promoted by the growth of the microorganisms or its metabolites is named microbial influenced corrosion (MIC), which occurs both in metal and non-metallic materials [6].
A large number of studies on microbial corrosion of the materials in recent decades have shown that virtually all common materials will produce corrosion caused by microorganisms.
The process of microbial influenced by corrosion involves many factors, such as the quality, the shape and the environment of the materials [9].
This plan mainly included microbial survival in cushioning materials in condition of radiation, high temperature and drought, migration of microorganisms in compacted cushioning materials, the corrosion that microorganisms possibly cause to the tank, microbial gas production in backfill material, the introduction of external things in the open cave, the presence and activity of microorganisms in deep granite groundwater, and the impact of biological barriers on the migration of radionuclide.
