Lastly, depending on physics equation of material which refers to the relationship between stress and strain, the stress was calculated by the strain.
Fig.1: Six kinds of topography unit Some suppositions are made as follow: there was no defect in the TBC system; ceramic coating and bond coat were bonded absolutely; the TBC system did not generate plastic deformation and creep deformation in the cooling process and all the material attributes were completely elastic; every layer material was isotropism.

Study on Extraction Technology of Chitin by Plant Iactobacillus Fermenting Shrimp Shell Protein Qianqian Liu1,a Hong Li2,b*, 1,2, School of Textile and Material Engineering of Dalian Polytechnic University, China a981188375@qq.com blihong@dlpu.edu.cn, Keywords: Abandoned shrimp shell;Extraction;Chitin ;Removing Protein; Plant lactobacillus; Fermentation Abstract.
Chitin has a wide range of application in food and biomedical fields.However, as a kind of any type of material, removing protein, extracting chitin from abandoned shrimp shell is a necessary stage.
Experimetal Materials Shrimp shell provited by Liaoning Fishery Group.Plant lactobacillus (l. plantarum) CICC6234 purchased from industrial microbial culture collection management center of China.

The influence of temperature in the material density is neglected; (2)Due to the very short heating time of the laser, the influences of the liquid flowing in the temperature field are not considered
When the laser mode is basic mode and the duty ratio K=0, the power distribution of circular laser spot is Gaussian Curve and the heat flow density can be simplified as follows: () (1) In the formula, P is laser power, A is laser absorption efficiency of materials, R is the maximum diameter of laser spot, rm is the distance from the random point in the laser spot to the center of the laser spot.

Fig.1 Engineering drawing of spiral bottom shell part The wall thickness of spiral bottom brake shell parts for heavy trucks is 2mm, its material is 08AL and shape and size is showed in fig.1.
Then, the blank used No.36 anisotropic elastoplastic material model provided by Dynaform, material type is SPCE (08AL in china) with thickness of 2.0mm.
Instead, too high of blank holder force would cause difficult flow of material and lead to tension crack.

The material constants of the U-shaped pipe are shown in Tab.1 and its mesh model is shown in Fig.1.
Tab.1 The material constants of the U-shaped pipe Material Density Elasticity modulus Poisson’s ratio Red copper 8.9 g/cm3 1.27×103GPa 0.3 Fig.1 The mesh model of the U-shaped pipe The finite element modal analysis results The natural frequencies of the U-shaped pipe are obtained through the following steps: 1) Import the finite element model, set the material constants and define the element type; 2) Mesh and define the loads; 3) Solve and view the results.
The error may be caused by the experimental environment, the experimental device and geometric model simplification in the experiment, and also may be caused by the material constants error in the finite element analysis.
