Robust damage assessment of multiple cracks based on the frequency response function and the Constitutive Relation Error updating method

KEY WORDS : finite element method; equilibrated stress recovery; constitutive relation error; error bounds; goal-oriented error

We introduce here a new method to obtain the Taylor series expansion of the objective function, called the Finite Element Method over a Polynomial Algebra (FEMPA), that keeps

ABSTRACT: In the following, a new analytical method, the Deformation Area Difference (DAD) method for damage assessment of bridge structures is applied using experimental test

Finally, the upper bound for the “online” error associated with the Galerkin-POD is obtained by comparison of the recovered stress field σ(µ) to the stress field b σ r (µ) obtained

Pseudo wholer’s plot: influence of the stress range on the number of cycles needed to develop a crack, twice the mean grain size in length, along path n84.... This is consistent

tiple reciprocity method [21, 22J which allows to transform the volume integral corresponding to a body force into an infinite series of boundary integrals using

This paper introduces an error estimator based on the constitutive relation which provides an upper bound of the global error for parametric linear elastic models computed with

In this paper, we have proposed a study of the enhanced error " enh on the constitutive relation in plasticity and shown that the calculation of this error estimator in order
