| Abstract | ||
| This paper introduces an attempt to study the dynamic analysis for laminated composite beam with bonded joints to investigate mainly the influences of lamina code number, bonded adhesive line configuration and boundary condition on the dynamic behavior of composite assembly. The mathematical finite element model (F.E.M.) by introducing unified mechanical parameters is represented to compute efficiently the eigen-nature for composite bonded structures. The experimental analysis is carried out using two techniques. The first includes ultrasonic technique which applies the magnetostractive pulse echo delay-line for material characteri-zation of composite material, while the second includes frequency response function using hammering method. The comparison between experimental and numerical model shows the efficiency of the proposed mathematical model of the composite structural beam with bonded joints. The results show that the changes of the eigen parameters provide a proper indicator for predicting the current state of adhesive bonded joint. | ||
