Research on the Methods of Determination of Characteristic Strength of Brittle Rock materials in Compression Test Bin WANG 1, a, Jie-bing ZHU 1,b , Ai-qing WU 1,c 1 Changjiang River Scientific Research Institute，Wuhan, 430010，China acugwangbin@163.com, bzhujb@vip.163.com, cwuaiqing@vip.sina.com Keywords: Brittle rock; crack closure; crack initiation; crack damage strength; damage threshold Abstract: The failure of rock materials in compression test suffers three characteristic stages: crack initiation, crack damage threshold, and macro-failure.
The AE monitoring method and the lateral P-wave or the axial S-wave test is an effective indicative of identifying the damage threshold when subject an axial compression failure. 1 Introduction Due to the long-term effects of various external loading and environmental actions, Rock materials internally exist a variety of defects such as micro-cracks, cavities, joints and so on.

In fact, there was a very close relationship between the physical and chemical properties of the materials and the formation of biofouling.
Model structures In this case, select the 22 kinds of surface materials from reference [5] as the training samples.
The predicting results showed that the model built could effectively predict the average biofouling amount of many kinds of materials.

The work is devoted to the basics of surface modification of structural materials for the effective protection of machine parts and mechanisms operated in extreme conditions from the mechanical impact of aggressive media, by the method of plasma-chemical exposure to concentrated streams of matter and energy by means of plasma generators, which allow for surface renovation and engineering.
The algorithm is based on the differential non-stationary equation of thermal conductivity inside the processed product , where – the material’s density, С – the specific heat capacity of the material, k – coefficient of thermal conductivity of the material, Q – energy source.
