| Abstract: | Taken the large size membrane steel plate turn-over lift case as an example,based on MSC Patran/Nastran finite element (FE) software,the structural response driven by gravity during the turn-over lift is analyzed by nonlinear finite element method. Cauchy stress result of the large-size membrane steel plate with usual thickness is listed for design. |
