The method uses a rectangle-parable stress distribution in the compression zone.
介绍一新的钢筋混凝土单筋梁的配筋计算方法和算例,该法在混凝土受压区采用矩形加抛物线的应力分布,在计算中求解的未知量是混凝土边缘压应变或受拉钢筋应变,而不是"等效矩形应力"法中的受压区高度。
The threat assessment model for SAM to penetration plane is established based on the multi-floor gray theory by using gray system theory combining with the application of the weight distribution based on nonlinear tree.
从研究航空兵对地空导弹突防作战背景出发,建立了地空导弹对突防飞机的威胁评估指标体系,并运用灰色系统理论,结合非线性树形分布权值分配法的应用,构建了基于多层次灰色理论的地空导弹对突防飞机的威胁评估模型,最后通过实例,对模型的有效性进行了检验。
On the basis of the mechanical principle of the stress function and its derivative on the boundry of elastomer and the method of Heaviside function, the stress calculation of the function of nonlinear distributed force on the undersurface of nonsymmetric wedge block has been obtained.
用应力函数及其导数在弹性体边界上的力学意义和海维赛（Ｈｅａｖｉｓｉｄｅ）函数的方法，对非对称楔形体在楔面下部承受非线性分布压力作用的问题进行了应力计算，给出了应力一般解并进行了讨论，其结果具有理论和实际意义。
