They are acquired as the solution to the eigenvalue problem of the dynamics of a 'cell' element augmented to fictitious boundary. Only the waves satisfying radiation conditions on the fictitious boundary are then used to depict the excitation via transfer function from the fictive boundary to the...
The hanger is modelled by finite element method (FEM). The relation between frequency and tension force is obtained from the eigenvalue equation of FEM model, and Genetic Algorithm method is utilized to solve the inverse eigenvalue problem. By matching the theoretical frequencies of analytical ...
This is done with the help of a novel linear eigenvalue problem in the framework of the Finite Element Method (FEM). Such a quantity is the radius of the first Frenet-curvature of a curve on the surface of an N-dimensional unit hypersphere, denoted as ρ. The reason why ρ is ...

In this paper, we study the solution of a certain non-smooth eigenvalue problem, using operator-splitting methods to solve an equivalent, constrained minimization problem. We present the Marchuk–Yanenko and Peaceman–Rachford schemes for solving the problem and compare their performance numerically ...
Isoparametric finite-element approximation of a Steklov eigenvalue problem We study the isoparametric variant of the finite-element method (FEM) for an approximation of Steklov eigenvalue problems for second-order, selfadjoint, el... A Andreev,T Todorov - 《Ima Journal of Numerical Analysis》 被引...
Finite element method (FEM) is an effective numerical method for the eigenvalue problems, and there have been many famous Refs. [6], [7], [8], [9], [10], [11], [12], [13]. In this paper, we consider the vibration problem on a bounded polygonal domain Ω⊆R2 occupied by ...
