| 摘 要： | 采用弹塑性理论研究了均布载荷作用下的矩形截面梁弹塑性弯曲问题，推导出了矩形截面悬臂梁的弹塑性弯曲挠度表达式，并重新推导出了矩形截面简支梁的弹塑性弯曲挠度表达式，更正了有关文献在研究均布载荷作用下矩形截面简支梁弹塑性弯曲时存在的错误．

| Abstract: | Based on elastic-plastic theory, elastic-plastic bending of the rectangular beam under uniformed load is researched and the deflection expression of elastic-plastic bending of rectangular cantilever beam is deduced. Then, the deflection expression of elastic-plastic bending of the simply supported beam of rectangular cross-section is reformulated and the error which exists in the relational paper in this field has been corrected. |
