The material for development of the sector chosen was austenitic stainless steel type 304L even though the material of construction of the inner vessel in the reactor is SS316LN, because of its tensile & forming behaviour being similar to that of SS316 LN.
The modelling details, friction factor, surface to surface contact details, size of mesh, material properties were used same as given in the published work carried out by Utpal Bohra et al. [7].
Material is assumed an isotropic and its properties are taken from RCC-MR 2012, Appendix A3.4S [9].

The resistance of concrete with cement replaced by zeolite to crack propagation was studied with respect to the life cycle of these materials [3].
Material, test specimens, and fracture tests Test specimens with nominal dimensions of 40 × 40 × 160 mm of fine-grained concrete, whose composition was based on the standard EN 196-1 Determination of cement strengths, were manufactured to determine the values of mechanical fracture parameters.
Table 5 also lists the relative values of the parameters compared to the reference material, with 100 % taken as the value of the parameter obtained for Ref.

Materials and Methods Quantities of 100kg of EAFD and 100kg of pig iron (hot metal at room temperature) were collected in industries in Espírito Santo state as follows: EAFD; ArcelorMittal/Cariacica and pig iron; Ucrânia Foundry located in the municipality of Serra.
In possession of raw materials, the next step was the chemical and physical characterization of the main raw materials through various characterization techniques.

Volume Meshing and Material Property Assignment.
Aimed to the biomaterial β-TCP, material property assignment for elastic mode is 46.267 MPa, and the poison ratio is 0.26 [5,6].
Considering the β-TCP is a brittle material, it would make the scaffold sensitive with the strain increased, so the 36%~41% interval is abandoned.

Research on Diagenetic Facies Based on Diagenetic Effect in the Low Permeability Sandstone Reservoir—A Case from C81 Reservoir in Huanjiang Region, Ordos Basin Chun Wang1,a, Zhiguo Jin2, Chengzhi Liu1 1 Faculty of Earth Sciences, Northeast Petroleum University, Daqing 163318, China 2 School of Energy Resources ,China University of Geosciences (Beijing), Beijing 100083,China awangchun0322@sina.com Keywords: Diagenetic facies, Diagenetic effects, Low permeability sandstone reservoirs, Ordos Basin Abstract.
The diagenetic effects on reservoir properties maybe come from all kinds of diagenesis processes, but it is mainly characterized by pore and interstitial material.
The characteristics of interstitial material.
Huanjiang Region C81 reservoir is mainly composed of dark-gray, gray and gray-white lithic feldspathic sandstone with low compositional maturity, the quartz content is 29.72~34.75%, feldspar content is 26.08~32.74%, detritus content is 19.94~27.57%.The average content of interstitial material reservoir is 13.44%, ferroan calcite is 3.66% and the hydromica content is 3.67%, they are the two main interstitial materials, followed by chlorite coating, siliceous, kaolinite and other interstitial material (Figure 1).
