本文在文献的基础上,用小弹塑性形变理论及线性稳定理论探讨了湿、热对几种铺层形式的复合材料多层和夹层圆桂曲板在轴压、侧压和剪切作用下的临界载荷的影响,给出了用试算法求解临界载荷的步骤及具体算例。本文的研究表明:湿、热对复合材料多层和夹层曲板临界载荷的影响较大,应引起足够的重视。 In this paper, based on the literature, this paper discusses the effect of wet and heat on the mechanical properties of several laminated composite materials and the laminated circular Gui Gui plate under axial compression, lateral pressure and shear under the condition of small elastic plastic deformation theory and linear stability theory. Of the critical load, the procedure of calculating the critical load with the test algorithm and the concrete example are given. The research in this paper shows that wet and heat have a great influence on the critical loads of the composite multi-layer and mezzanine curved plates, which should be paid enough attention.
