  simply supported annular plate
The elasto-plastic bending of a simply supported annular plate with a free inner edge upon which an uniformly distributed lateral load acts is theoretically investigated, taking into account the influence of the membrane forces.
      


The exact yield conditions for perfectly plastic thin shells are given in terms of the six generalized stresses nx, ny, nxy, mx, my, mxy, which, however, are too complicated to use. This paper introduces two parameters, namely, the intensity of membrane forces n = f (nx ny, nxy) and the intensity of moments m = f (.mx, my, mxy), where f(σx, σy,σxy) = σs is the yield criterion for the shell material. The two parameters n and m are used to give approximate yield surfaces φ(n, m)=1, which are also called the limited...

The exact yield conditions for perfectly plastic thin shells are given in terms of the six generalized stresses nx, ny, nxy, mx, my, mxy, which, however, are too complicated to use. This paper introduces two parameters, namely, the intensity of membrane forces n = f (nx ny, nxy) and the intensity of moments m = f (.mx, my, mxy), where f(σx, σy,σxy) = σs is the yield criterion for the shell material. The two parameters n and m are used to give approximate yield surfaces φ(n, m)=1, which are also called the limited interaction yield surfaces. The best yield surface inscribed to the exact one is n2+m=1, and the circumscribed one is max{n, m} = 1.The paper suggests that the independent interaction yield surfaces max = 1may be used to find the collapse loads of the shells. If n0 and m0 are chosen to satisfy n02+m0=1, one may obtain a fairly good lower bound for the collapse load. If n0=m0=1, one may obtain an upper bound. A simply supported annular plate under combined tension and bending is taken as an example to illustrate the easy use of the approximate yield surfaces. Finally, the application of the independent interaction yield surfaces in solving the shallow shell problems is discussed briefly.

理想塑性薄壳的精确屈服条件是以六个广义内力n_x,n_y,n_(xy),m_x,m_y,m_(xy)来表达的,它们十分复杂,不便应用.本文按壳体材料在平面应力状态的屈服准则,f(σ_x,σ_y,σ(xy))=σ_s下引入膜力强度n=f(n_x,n_y,n_(xy))和力矩强度m=f(m_x,m_y,m(xy))这两个参数,导出了弱作用近似屈服面φ(n,m)=1;给出了精确屈服面的最优内接屈服面为n~2+m=1,外接屈服面之一为max{n,m}=1. 文中建议利用独立作用屈服面max{n/n_o,m/m_o)=1来计算壳体的承载能力;再取n_o~2+m_o=1,就能给出相当好的下限,取n_o=m_o=1,则能给出一个上限;最后并以同时受拉伸和弯曲的简支环板为例,说明了这个屈服面的应用是十分简单的;以均布载荷作用下周界不可移椭圆抛物面扁壳为例,简单讨论了独立作用屈服面在求解非轴对称扁壳问题中的应用.

In this paper, the Prager-Sheld optimality criterion is applied to discuss the optimization of the annular plate having simple support. We present a Ⅱ-type solution which generalizes the work reported in the reference [1]. We also study the optimal support locations for annular simple support plate with selfweight. Last, the cost intelligent degree is calculated and the duality principle is appied in order to test the reliability of our method.

In this paper, on the basis of the reference[1],further, the generalized step function is applied to the plastic limit analysis of annular plates under complicated loads. It aims to clampd and simply supported annular plates at outside boundary supporting. The three possible distribution form on local uniform and linear load have been considered. The calculating formulas of limit load of annular plates have been given out by generalized step function.
