This paper deals with the characterization by Acoustic Emission technique of damages occurring in a hybrid laminate aluminium/glass during quasi-static and fatigue tests. Indeed, laminates materials metal/composites are more considered structure, automotive aerospace designs because their good mechanical performances lightness. To understand characteristics, several types (fiber orientations, number folds, presence or not an aluminium sheet) have been tested. The acoustic emission analysis...

Abstract The fatigue life of overhead conductors is usually evaluated through experimental tests on clamp/conductor assemblies. Some recent studies aim to estimate the using uniaxial individual strands. This paper presents an innovative method for assessing fretting combining effect both tension and bending loadings. It consists coupling a numerical approach based modeling assembly finite element one wires. A biaxial test rig has been developed validated preliminary performed 1350‐H19...

The use of adhesively bonded carbon fiber reinforced polymer (CFRP) materials to reinforce cracked steel elements has gained widespread acceptance in order extend the lifespan metallic structures. This allows an important reduction stress intensity factor (SIF) at crack tip and thus a significant increase fatigue life. paper deals with assessment SIF for repaired plates, using semi-empirical analysis finite element analysis. Metallic plates only one originating from center hole were...

Reliable use of Shape Memory Alloys (SMA) in mitigation extreme load effects requires a deep study the SMA behavior according to necessities application. Damping oscillations induced by one storm three or four days with strong wind and/or rain usually more than million working cycles. A damper is checked two realistic cables ELSA and IFSTTAR. The measurements establish that damping device reduces drastically oscillation amplitude. Technical suggestions for preparation dampers built several...

The properties of SMA (Shape Memory Alloys, smart materials) are associated to a first order phase transition named martensitic transformation that occurs between metastable phases: austenite and martensite. At higher temperature or at lower stress the is phase. martensite appears stresses. hysteresis permits different levels applications, i.e., in their use as damper. Two types applications can be considered damping structures Civil Engineering. one related diminishing damage induced by...

The well-known martensitic transformation is not always the unique solid-solid phase change in NiTi shape memory alloys (SMA). For this material, R-phase can occur from both austenite and martensite. In some applications, macroscopic strain of material be limited to 2%. these cases, contribution neglected anymore when compared with Furthermore, different thermomechanical couplings have taken into account carefully predict rate effects better describe application conditions. paper, a new...

The exploitation and harnessing of offshore marine renewable energy have led to an increased demand for reliable power cables with long service lives. These constitute a considerable share the total installation cost facilities high maintenance repair costs. critical characteristics these must be determined reduce risk exceeding their ultimate strength or fatigue life, which can result in unwanted unexpected failures. This study investigates dynamic that are suitable application devices...

Les câbles actuellement utilisés en génie civil, notamment sur les ponts à haubans ou suspendus, sont constitués de fils d'acier cylindriques diamètre compris entre 3 et 7 mm. Ils acier non peu allié composition proche l'eutectoïde obtenus par tréfilage froid. ont une résistance la traction élevée (supérieure 1900 MPa) faible ductilité. De leur constitution, présentent bonne robustesse rigidité flexion. Cependant, études conduites ces dernières années montré que principales causes...

Superelastic Shape Memory Alloys (SMAs) provide a high damping capacity due to the hysteretic motion of inter-phase boundaries during martensitic transformation. They have demonstrated their ability control vibrations SMA-based Civil Engineering and Aerospace structures. In order improve existing devices, characterization SMA is necessary, despite lack standard procedure. Classical characterizations such as tensile or torsion tests on samples are very attractive, fact that they common simple...
