Finite element analysis of nonlinear oscillators
International Journal for Numerical Methods in Engineering, 1985AbstractPresented in this paper is a finite element method for the analysis of nonlinear oscillations which exhibit periodic response. The basic idea of the method is to recast the initial value problem as a boundary value problem in which the domain (that is, period) may be unknown.

An application of the Kantorovich theoremto nonlinear finite element analysis
Numerische Mathematik, 1999The author proves the existence as well as a priori error estimates for a finite element solution to a nonlinear problem by means of the Kantorovich theorem. This theorem is more known in the context of the numerical solution using Newton's iteration. The problem under consideration covers elliptic boundary value problems in 1, 2, or 3 dimensions with ...

Nonlinear Finite Element Analysis of FQQB
Applied Mechanics and Materials, 2013The mechanical properties of the whole wall and the wall with openings under vertical loads are analyzed by nonlinearity finite element method (NFEM). The results show that the stress of steel wire has a direct relationship with the load form. The inclined plug wire mainly carries the stress caused by load differences between the two sides of concrete,

Geometrically Nonlinear Finite-Element Analysis
Journal of the Engineering Mechanics Division, 1969The procedure for extending the finite-element displacement method to include geometric nonlinearity is outlined and a consistent formulation applicable to arbitrary plate and shallow shell elements is derived. Examples illustrating the application of a rectangular element to a plate, a shallow cylindrical shell, and a shallow hyperbolic paraboloid are

Arc-length technique for nonlinear finite element analysis
Journal of Zhejiang University-SCIENCE A, 2004Nonlinear solution of reinforced concrete structures, particularly complete load-deflection response, requires tracing of the equilibrium path and proper treatment of the limit and bifurcation points. In this regard, ordinary solution techniques lead to instability near the limit points and also have problems in case of snap-through and snap-back. Thus

Bayesian sensitivity analysis of a nonlinear finite element model
Mechanical Systems and Signal Processing, 2012Abstract A major problem in uncertainty and sensitivity analysis is that the computational cost of propagating probabilistic uncertainty through large nonlinear models can be prohibitive when using conventional methods (such as Monte Carlo methods). A powerful solution to this problem is to use an emulator, which is a mathematical representation of ...

Computerized symbolic manipulation in nonlinear finite element analysis
Computers & Structures, 1981The potential of using computerized symbolic manipulation in the development of nonlinear finite elements is discussed. Three tasks which can be efficiently performed using computerized symbolic manipulation are identified: (1) generation of algebraic expressions for the stiffness coefficients of nonlinear finite elements, (2) generation of FORTRAN ...

Nonlinear finite element analysis of sandwich shells of revolution
13th Structures, Structural Dynamics, and Materials Conference, 1972The nonlinear bending and buckling problems of axisvmmetric three-layered sandwich shells are solved using an incremental finite element approach. The nonlinearities considered are due to large displacements, and plastic deformations of the facings.
