Lecheb, SamirNour, AbdelkaderChellil, AhmedLechani, R.Kebir, H.2015-06-112015-06-11201412th International Conference on Fracture and Damage Mechanics, FDM 2013; Sardinia; Italy; 17 September 2013 through 19 September 2013; Code 10121310139826https://dspace.univ-boumerdes.dz123456789/1652This paper based to study of the dynamic and fatigue behaviors with numerical and experimental parts of a composite material manufactured by stacking two layers of E-glass fiber in different angle orientations (0°/90°) immersed in polyester resin with total thickness 1.39mm. In Finite Element Analysis (FEA) using ABAQUS was used to evaluate the maximal (displacement, strain and stress) and the natural frequencies (mode shapes) of composite behavior under crack initiation condition. In the experimental part the laminate plate specimen with two layers is tested under one types of cyclic load in fully reversible tensile at (R=0), the fast fracture occur phenomenon and the fatigue life are presented, the fatigue testing exerted in INSTRON 8801 machine.enAngle orientationComposite behaviorDynamic behaviorsE-glass fibersFatigue crack initiationLaminate platesStrain and stressABAQUSFatigue of materialsFatigue testingGlass fibersNatural frequenciesFracture testingArticle
