Structural-model experiments revealing bifurcation, instability and localization
… to analyze several aspects of instability and bifurcation occurring in structures and within materials. Photoelasticity is employed to analyze the localization of stress in ordered granular materials and near stiff and thin inclusions embedded in an elastic matrix. Prototypes have been …

Vibration Analysis of Cracked Composite Bending-torsion Beams for Damage Diagnosis
… concept is implemented to model the open crack and the associated compliance matrix is derived. The crack introduces additional boundary conditions at the crack location and these effects in conjunction with those of material properties are investigated. Free vibration analysis of the cracked …

Aeroelastic behaviour of composite wings
… of investigations into the structural, dynamic and aeroelastic behaviour of composite wings. The study begins with a literature review where the development of aeroelastic tailoring and specific applications of the technology are discussed in detail. A critique of methods for the determination …

Aeroelastic modelling of gyroplane rotors
… the first successful rotorcraft design and it paved the way for the development of the helicopter during the 1940s. Gyroplane rotors are not powered in flight and work in autorotative regime and hence the characteristics of a helicopter rotor during powered flight and a rotor in …

Aerodynamic and Electromechanical Design, Modeling and Implementation Of Piezocomposite Airfoils
Piezoelectrics offer high actuation authority and sensing over a wide range of frequencies. A Macro-Fiber Composite is a type of piezoelectric device that offers structural flexibility and high actuation authority. A challenge with piezoelectric actuators is that they require high voltage input; …
