Finite Elements by Dietrich Braess
Is the real error overestimated or underestimated if merely the error with respect to the elejente solution is evaluated? Shear correction factors are disregarded in the text.
This definitive introduction to finite element methods was thoroughly updated for this third edition, which features important material for both research and application of the finite element method. To see what your friends thought of this book, please sign up.
Obviously, the distance to the P 4 solution does not reflect the distance to the true solution in this case. A posteriori error estimation for lowest order Raviart Thomas mixed finite elements.
D. Braess – Finite Elemente – Extensions and Corrections
Jarmo Van Rooij marked it as to-read Sep 22, Return to Book Page. The proof of the lower bound 8.
Although not explicitly stated, the results show that Hypothesis H2 makes the plates stiffer than they are. It follows that P 4 elements yield a solution with an error that is smaller than the error for P 1 elements multiplied by a factor smaller than 1, provided that we disregard terms arising from data oscillation.
In “Plates and Shells, Quebec “, M. Oswald, Divergence of FEM: This was described by Marini  and in a less obvious way by Arnold and Brezzi  in Theorem 2. Thanks for telling us about the problem. Trivia About Finite Elements. The use of techniques from a posteriori estimates for the a priori analysis of plates has a different reason. It is efficient since the error of the mixed method is not dominant; see Theorem 5.
Floietoss added it Mar 30, It is not only used for a posteriori error estimates, but also for a justification of plate models; cf. The stiffness matrix for the model problem was determined here in a node-oriented way. Thus shape regularity or a similar condition is required. The converse is required if an efficient estimator for the Raviart-Thomas element is wanted.

Daniel Ganellari added it Feb 14, Derivation and justification of plate models by variational methods. Aluizio Albuquerque marked it as to-read May elementr, An Example is the cantilever beam Fig. Refresh and try again. Nqvgz rated it really liked it Jan 15, The a posteriori estimator in Theorem 9.
To ask other readers questions about Finite Elementsplease sign up. The counterexample of a domain with a cusp shows that there is no implication in the converse direction. Shape regularity may be formulated as a condition on the angles of the triangles in a triangulation. Open Preview See a Problem?
The discussion of saddle-point problems is a highlight of the book and has been elaborated to include many more nonstandard applications. Note that rot v is also large.
