β¦ Synopsis
TlLe errors ipa structural com@ations are a,ssessed and bounds aye established on their magnitude. The matrix decomposition approuch is shown to be most useful in error analysis. Both positive definite and positive semi-dejkite matrices are treated. T?ie &scretefLnite-digit representation qf Ilumbers in a digital computer and the nature of digital computer calculations are considered in the development.

We present a symbolic technique of error analysis of numerical algorithms, which acts as a preprocessor to the actual numerical computation. The technique provides rigorous, a priori bounds which are universal for inputs in a prescribed domain. The method is an alternative to interval arithmetic in
This paper focuses on an a posteriori error estimator for FE approximations of 3D linear elasticity problems. The objective is to present the application of the new generation of error in constitutive relation to the calculation of the local error in classical tetrahedral elements. We show on exampl
