I was wondering if there any efficient methods with the least error (e.g., trapezoid method may generate too errorneous answers.). AND more importantly, are there any features in the signal processing and communucation app in matlab that facilitates such a signal processing to cinvert th...
However, for elastoplastic contact, current numerical methods require a long calculation time. Hyperelastic contact is typically simplifed to a linear elastic contact problem, which must be improved in terms of calculation accuracy. Based on the fast Fourier transform, a numerical method suitable for ...

Yes, and in many different ways. FPI 是否收敛取决于 S=|g'(r)| <1. - FPI 只是locally convergent,收敛速度为S - 0<S<1/2,FPI 收敛速度优于Bisection Method。 S=1/2, FPI 收敛速度等于Bisection Method。 1/2<S,FPI 收敛速度坏于Bisection Method。如果S>=1, FPI发散; - - P45 --- 考虑...
Traversing the contour in reverse order is equivalent to using another Vandermonde matrix as the transformation matrix. Our paper provides experimental results that show that this method does not work. The literature describes two algorithms that generalize the FFT on the unit circle: the Chirp ...
The code has an explicit multi-step Runge Kutta time integration method. Implicit time integration methods can be implemented in Fierro. Usage Anaconda The recommended way to use Fierro is through the provided Anaconda package. To use the anaconda package, follow the steps for your platform to ...
Based on FFT, a numerical method suitable for elastoplastic and hyperelastic frictionless contact is proposed in this paper, which can be used to solve 2D and 3D contact problems. The non-linear elastic contact problem is transformed to linear elastic contact considering residual deformation (or equi...
