| Abstract: | According to the principle of minimum potential energy with mixed variable for beams with large deflections, the deflection equations of cylindrical bending of infinite-length rectangular plate in different limit conditions are calculated. In contrast with classic results, the results obtained in this paper have a higher accuracy. |
