英文摘要: |
This paper introduced the background of the research,it analyzed the principle and the development of several
common structural sensitivity analysis methods based on the finite element method. including analysis method, global
finite differences. semi-analysis finite element method, complex variable method and the adjoint variable method.
Finally, According to the sensitivity study of the recent years, the combination of the multiple sensitivity analysis is the
development trend of future structural sensitivity analysis. |
