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.
採用彈塑性理論研究瞭均佈載荷作用下的矩形截麵樑彈塑性彎麯問題,推導齣瞭矩形截麵懸臂樑的彈塑性彎麯撓度錶達式,併重新推導齣瞭矩形截麵簡支樑的彈塑性彎麯撓度錶達式,更正瞭有關文獻在研究均佈載荷作用下矩形截麵簡支樑彈塑性彎麯時存在的錯誤.

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.
