之前在使用一款力学仿真软件(Openfast)计算时,总是出现不收敛的问题,怀疑是数值计算问题。所以后面详细的分析了其中使用的广义α法的收敛性。 动力学数值求解方法常用叠加法(Duhamel 积分)、直接积分法(如newmark-beta法),Generalized- α 法是直接积分法的一种。 以单自由度动力学系统为例,对Generalized- α 方法计...

Generalized Alpha-Close-to-Convex FunctionsConvex Functionsthese classesclassesWe define the classes G_β(α, k, γ) as follows: f∈G_β(α,k, if and only if, for z∈E={C:|z| < 1), |arg { (1 - α~2z~2)f'(z)/ e~(-iβ)φ'(z)}|≤γπ/2, 0 γ≤ 1; α∈[0,1]...
High-order generalized-alpha methodThe generalized-method encompasses a wide range of time integrators. The method possesses high-frequency dissipation while minimizing unwanted low-frequency dissipation. Additionally, the numerical dissipation can be controlled by the user by setting a single parameter, ...

The paper provided a new notion of neutrosophic separation axioms as neutrosophic gαg-Ri-space & neutrosophic gαg-Tj-space (note that the indexes i & j are natural numbers of the spaces R & T are from 0 to 1 & from 0 to 2 alternately)....
