The aim of this study is to analyse the mechanical properties of low alloy steel 42CrMo4, used for the manufacture of bolts and threaded roads by Oil Company. We consider an experimental approach based on tensile, impact ...

This work presents a numerical study of a 2D oscillatory flow around different cylinders with elliptical section, under the conditions of three modes of vortex-shedding: regime "A" (Re = 100 and KC = 5) regime "D" (Re = ...

Composite materials have been used to structurally repair piping and other facilities for many years. However, the original use of composite materials was for repairing corroded pipelines where the intent was to restore ...

Liquefaction is a process in which, saturated looses temporarily its strength and behave like a liquid. The work in this thesis is a contribution in an analyzing the behavior of granular soils under monotonic loading. ...

Because of the specificities of self-compacting concrete (SCC), especially regarding their high volume paste content and the presence of large amounts of mineral admixtures and substitutes, the behavior in fresh and hardened ...

IV Abstract This work studies one of the most important and complex phenomena of soil dynamics that is the liquefaction. A bibliographical study of the phenomenon, mechanisms and theoretical approaches used in the estimation ...

In this thesis, a numerical model was developed to simulate the coupled heat, air and moisture transport in unsaturated porous materials. The state of the art knowledge of heat and mass transfer in unsaturated porous ...

This research addresses the influence of the seismic component of rotation on the torsional response of building structures subjected to earthquake ground motions. Furthermore, the increase an equivalent additional ...

The work of this thesis is to undertake an experimental study on the behavior of a sand liquefaction and also the effect of some parameters on the mechanical behavior of the soil. It is presented in this work a bibliographical ...

This paper presents a self compacting cement paste formulation using Algerian local materials (binary cement consisting of natural pozzolana and limestone fillers). In this study, simple laboratory instruments were used ...
