本期实战一个用Newton–Raphson Method求解非线性方程组根的例子。 使用Newton–Raphson方法,求解下述非线性弹簧的两个节点位移。使用1×10-5的收敛误差和初始估计u0= [0,0]T 。同时,估计收敛速度。 考虑两个串联的非线性弹簧,如Fig. 1所示。两个弹簧的刚度取决于弹簧的伸长率,其中 k1 =50+500u
本期对Modified Newton–Raphson Method的收敛性进行一个深入讨论。Newton–Raphson方法要求在每次迭代时,应形成雅可比矩阵,并应针对解的增量求解线性化方程组。从计算角度来看,这些都是昂贵的任务。在有限元框架中,建立切线刚度矩阵和求解矩阵方程是计算量最大的两个过程。而Modified Newton–Raphson方法因此而产生,它试...

MATLAB Online で開く I want to approximate the zeros of the following nonlinear system, using N-R method: f(x,y)=x+y^9/3+x^{243}/9+y^{2187}/27=0; g(x,y)=y+x^{27}/3+y^{243}/9+x^{6561}/27=0. I have tried with the following M...
Modified Newton–Raphson method不需要重新计算切线刚度矩阵,而是在所有的迭代步中都使用初始切线刚度矩阵,因此又称为常刚度迭代。如图所示 Modified Newton–Raphson method往往需要更多的迭代步数,但是得到最终解的计算过程可能会更少。此外,此方法更稳定,不易发散。
