摘要 为了解决极限强度计算时曲板能否作为硬角单元的问题,从曲板屈曲的规范公式出发,讨论曲板屈曲与几何参数的关系。采用非线性有限元程序对具有不同初始缺陷的多组曲板进行极限强度计算,研究初始缺陷对曲板极限屈曲强度的影响。依据是否发生屈曲,给出判定曲板归属硬角单元的判据。 In order to solve the problem of whether the curved plate can be used as a hard angle element in the ultimate strength calculation, the relationship between the buckling of the curved plate and the geometric parameters is discussed from the standard formula of curved plate. By the nonlinear finite element program, the ultimate strength calculations of curved plates with different initial imperfections are carried out. The effect of initial imperfection on the ultimate buckling strength of curved plates is investigated. According to whether it is buckling or not, a criterion is proposed to determine whether the curved plate belongs to the hard angle element.
