Multilevel Projection Algorithm for Solving Obstacle Problems
K e y w o r d s O b s t a c l e problem, Multilevel projection, Convergence, Finite element, Error estimate. 1 . I N T R O D U C T I O N The obstacle problem we consider here can be described as follows: find the equilibrium position u = u(x), x E f~ C R 2 of an elastic membrane constrained to lie above a given obstacle @ = @(x) under an external force f (x ) . Then u(x) is the formal solution ...
متن کاملAn algorithm for solving the double obstacle problems
In this paper, we extend the algorithm in Xue and Cheng [L. Xue, X.L. Cheng, An algorithm for solving the obstacle problems, Comput. Math. Appl. 48 (2004) 1651–1657] for solving the double obstacle problem. We try to find the approximated region of the contact in the double obstacle problem with less computation time by iteration. Numerical example is given for the double obstacle problem for t...
متن کاملCubic splines method for solving fourth-order obstacle problems
In this paper, we develop a new cubic spline method for computing approximate solution of a system of fourth-order boundary value problems associated with obstacle, unilateral and contact problems. It is shown that the present method is of order two and gives approximations which are better than those produced by some other collocation, finite difference and spline methods. Numerical examples a...
متن کاملOn Guaranteed Accuracy Computation
The concept of guaranteed accuracy computation is a natural one: the user could specify any á priori relative or absolute precision bound on the numerical values which are to be computed in an algorithm. It is a generalization of guaranteed sign computation, a concept originally proposed to solve the ubiquitous problem of non-robustness in geometric algorithms. In this paper, we investigate som...
متن کاملCalculating Bifurcation Points with Guaranteed Accuracy
This paper presents a method of calculating an interval including a bifurcation point. Turning points, simple bifurcation points, symmetry breaking bifurcation points and hysteresis points are calculated with guaranteed accuracy by the extended systems for them and by the Krawczyk-based interval validation method. Taking several examples, the results of validation are also presented. key words:...
