Mastery Motivation and Developmental Delayes and installation costs. The objective of this study is to highlight the various mechanisms of rupture of polyethylene pipes in service and in laboratory conditions under fatigue and creep loadings. It is known is some cases that at least two mechanisms control PE pipe failures based on results cu

Defect Assessment on Pipe Transporting a Mixture of Natural Gas and Hydrogen,trolled by a cathodic polarisation method. Fracture toughness for blunt pipe defect such as dent is measured on “roman tile specimen”. It can be determined either critical J parameter or critical notch stress intensity factor. Then the defect assessment is made using a notch modified failure assessment diagramme (NMFAD).

Prediction of Structural and Dynamic Behaviors of Impacted Plates,t impact parameters. The obtained results are in good agreement with those given with the finite element simulations. The validated model has been used to study the distribution of the stress field and its evolution under the effect of the different impact parameters.

PCA method is based on the statistical analysis, thus partial virtual coherence and multiple virtual coherence are used to quantify the coherent shares with the acquired signals autospectres.

Definition of Reliability and Riskhip between hydrogen concentration and critical (failure) loading has been found. Also, the existence of some critical hydrogen concentration, which causes the significant loss of local fracture resistance of material, was shown.
