Deformation Characteristics of Composite Structures
The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...
متن کاملAnalysis of Nonlinear Vibro-Acoustic Wave Modulations Used for Impact Damage Detection in Composite Structures
Composite materials have been widely used in many advanced engineering structures. High specific strength, light weight, resistance to fatigue/corrosion and flexibility in design displayed by these materials have benefited many industries especially in the transportation area. Despite of all these benefits the susceptibility of composite materials to incur impact damage is well known and create...

متن کاملStructural-Acoustic Optimization of Composite Sandwich Structures: A Review
We review recent advances in the area of composite sandwich modeling, sensitivity analyses, optimization techniques and applications, with the focus on structuralacoustic problems. The optimization of sandwich structures is with respect to passive design parameters, such as material constants, geometric parameters, cellular core geometry and boundary conditions.
متن کاملNumerical and Experimental Acoustic Performance Investigations of a High-Speed Train Composite Sandwich Panel
Present work focuses on the implementation of numerical and experimental analyses aimed to acoustic performances characterization of a composite sandwich panel used for a high-speed train. Firstly, an experimental and a numerical modal analyses are presented. Starting from both FE simulation and impact testing outcomes, it has been possible to carry out a correlation study through the computati...
