| Abstract: |
| In this paper,the feasibilities for hydro-elastic-plastic model with four famous fluid dynamics numerical methods,namely,CE/SE,CIP,Roe and MUSCL are investigated.The mechanical process involving strong discontinuity in elastic mediums and the one-dimensional shock tube problem are simulated,by using the four methods.By analyzing the numerical results carefully,one could preliminarily conclude that CE/SE method and MUSCL method are better for solving hydro-elastic-plastic problems.Due to the clear physics concepts in the construction process and the higher-resolution,CE/SE method is the most suitable for computing hydro-elastic-plastic problems in the four schemes.To test the capability in detail,CE/SE method is also performed to simulate a hydro-elastic-plastic problem,which is the wavy interface generation process in explosive welding of steel-copper plates and aluminum-copper plates.The computational results are very similar to the experimental ones. |
