摘要
对理想弹塑性材料的梁,通过引入弹塑性弯曲刚度(EI)p 与相应弯矩M 之间的近似函数关系,使等截面梁的弹塑性弯曲问题,转化为变刚度的弹性弯曲问题.从而在弹性范围内求梁变形的方法也适用于弹塑性阶段,且具有较高的精度.
Throngh introducing the idea of approximate functional relationship between elastoplastic bending stiffness(EI)p and its eorresponding moment M to the ideal elastoplastic beam,we can transfer the problem of elastoplastic bending of equal section beam into the problem of elastic bending of modified stiffness.Thus,the method for the determination of beam deformation within the elastic limit is also applicable to the elastoplastic stage and having higher accuracy.
