Since these materials serve important functions in systems, quantifying changes occurring in the material’s chemical, physical, and mechanical properties over the system lifetime is observable[3].
The result is a large scatter for the results of standard testing methods and a distinct difficulty in obtaining rational assembly stress assessments for these materials.
Followed, prediction of 10,000 sets of assembly stress is completed by Monte Carlo random sampling materials model parameters.

Study on the Technologies of Rapid Three-dimension Optical Measurement for Welding Deformation of Sheet Materials Zhenzhong XIAO1, a, Jin LIANG1,b, Dehong YU 1,c , Zhengzong TANG 1,d 1 School of Mechanical Engineering, Xi'an Jiaotong University, Xi'an 710049, China a xiaozhenzhong@163.com, bliangjin@x263.net, cdhyu@xjtu.edu.cn, d tangzhengzong@stu.xjtu.edu.cn Keywords: Welding Deformation, Sheet Metal, 3D Optical Measurement, Deformation Control Abstract.
The application in the measurement for welding deformation of sheet materials is satisfying.
The material in the area with high temperature expands during heating and shrinks during cooling, but it can not deform freely, then there is internal stress generated in the welding that deforms the material of this part by extrusion and tension.
Conclusions This paper proposes a new non-contact rapid 3D optical method to measure real-time welding deformation of sheet materials.

As the mass of collapses and landslides, a wealth of loose solid materials are directly provided to debris flow movement, and the instability of slope and the damage of rock mass are caused by the earthquake., so these debris flow ditches will stay in the active phase for the next long period, the outbreak scale and frequency of debris flow will be increased significantly.

Due to their unique properties, they are widely used in modern technologies, are part of a large number of devices and materials and are also used as catalysts for various chemical processes [2, 3, 4, 5, 6].
The most significant deposits of rare earth metals, such as Bayan Obo, are of hydrothermal origin; therefore, the study of the complex formation of rare earth metals in aqueous solutions is an urgent problem for modern science.
