Anti-plane Scattering And Seismic Ground Motion Of A Rectangular Hill With SH Wave

In civil engineering , seismic design of structures are more and more attention than others,the structure of the dam or hydraulic seems to bump into a square structure about this paper.According to the fluctuation theory of finite element and finite element software ANSYS, it simulated in SH scattering and dynamic stress concentration square hill underwave action and other issues.Firstly, it introduced the causes of earthquakes and earthquake mechanism and saummarize a brief description,The seismic waves in the actual meaning was described in a brief introduction to the knowledge of elastic mechanics and numerical calculations on the basis of elastic mechanics,then it leads to be some fluctuations in the finite element theory .A brief description how to determine the artificial borders is decided to determine the size of the loaded model and other issues . After the completion of this task, we have established a finite element model with different media and the same one. The finite element model will simulate and analyze the results of numerical simulations . The equivalent figure derived anti-plane displacement and stress of each displacement nodes , speed and acceleration of the comparison chart, then is used to make the theoretical knowledge to analyze these results and give possible causes of the above results,the results can provide a reference for the actual project.
