Active vibration control of composite structures
The vibration control of composite beams and plates subjected to a travelling load is studied in this dissertation. By comparing the controlled as well as uncontrolled responses of classical and refined structural models, the influence of several important composite structure properties which are …

Multifunctional composite structures with damage sensing capabilities
… promising routes for developing multifunctional composite structures with damage sensing capabilities towards the development of integrated non-destructive inspection (NDI) and structural health monitoring (SHM) capabilities. Two routes were identified and selected for further investigation; the …

LS-Dyna for Crashworthiness of Composite Structures
<p>Composite materials have excellent mechanical and thermal properties and are the materials of choice for many applications. Even though, the low inter-laminar mechanical properties and poor impact resistance of fiber reinforced composite materials has limited their use. The study of axial …

Progressive failure analysis of laminated composite structures
… analysis is presented that is applicable to thin composite structures undergoing large deformations. The method is based on a nonlinear shell theory that accounts for geometric and material nonlinearities. An isoparametric, displacement-based finite element formulation is used to discretize the …

Optimization of composite structures by genetic algorithms
The design of composite laminated panels is a combinatorial problem when the orientation of the fibers in each layer is restricted to a discrete pool of angles. Additionally, composite laminates often have many optimal and near-optimal designs, and the designer may benefit by knowing many of those …

Nonlinear Vibrations of Metallic and Composite Structures
… several studies into the dynamic response of structures are made. In all the studies there is an interaction between the theoretical and experimental work that lead to important results. In the first study, previous theoretical results for the single-mode response of a parametrically excited …

Progressive Failure Analysis of Laminated Composite Structures
Laminated composite structures have started to play a very significant role in today's aircraft industry. The application of composite materials has now gone beyond the borders of aircraft design and has entered into such fields as automotive, athletics and recreational equipment, etc. The light …

Combined Tension-Torsion Loading of Braided Composite Structures
Braided composites are a class of composite materials. They feature an inter-woven structure that improves structural stability and damage tolerance. Presently, braided composites under tension and torsion loading have been studied individually. Mechanical behaviour of braided composites under …

Behaviour of demountable shear connectors in composite structures
… as an alternative to welded shear connectors in composite structures through push off tests and composite beam tests. Push off tests were conducted to examine the shear strength, stiffness and ductility of demountable shear connectors in composite structures. The experimental results showed that …

Nondestructive evaluation and underwater repair of composite structures
Composite materials are gaining popularity in U.S. Naval applications because of their unparalleled strength, stiffness, and manufacturing simplicity. A better understanding of the structural integrity of these materials has the potential to reduce overdesign, decrease manufacturing cost, and …

Probabilistic aspects of progressive damage in composite structures
… of the progression of damage in the analysis of composite structures are assessed. Two specific cases of graphite/epoxy with centrally-located holes are considered: a [0/90/±45], laminate subjected to equal biaxial tension, and a [±15/0],, laminate subjected to uniaxial tension. The variation in …

Buckling, Flutter, and Postbuckling Optimization of Composite Structures
… with the design and optimization of a large composite structure. In design of large structural systems, it is customary to divide the problem into many smaller independent/semi-independent local design problems. For example, the wing structure design problem is decomposed into several local …
