Free vibration characteristics of continuous grading fiber orientation (CGFO) beams resting on variable Winkler and two-parameter elastic foundations have been studied. The beam is under different boundary conditions and assumed to have arbitrary variations of fiber orientation in the thickness direction. The governing differential equations for beam vibration are being solved using Generalized...

Multifunctional materials facilitate lightweight and slender structural solutions for numerous applications. In transportation, construction that can act as a battery, store electrical energy, will contribute to realization of highly energy efficient vehicles aircraft. Herein, multicell battery composite laminate, with three state-of-the-art cells connected in series is demonstrated. The experi...

Glass fiber-reinforced polymer (GFRP) ship structures have hull plate thicknesses of 10 mm or more and are fabricated using a higher proportion resin matrix systems than E-glass fiber reinforcements. Therefore, GFRP is classified as highly attenuative material, this characteristic major cause large errors in ultrasonic nondestructive testing for quality inspections. In study, considering the af...

Possibilities for the " parasitic " collection of power from human walking motion are explored. The focus is on the walking action as a source of power because of the extensive range of motion and large dynamic forces associated with the heel strike and the bending of the sole. Two piezoelectric systems: a multilayer laminate made from PVDF foil and a unimorph piezoceramic composite (PZT); as w...

The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite el...

A Model to Predict the Long-Term Strength of E-Glass Fiber Composites Subjected to Environmental Exposure Thomas Miles Damiani Glass Fiber Reinforced Plastics (FRP) are being used in an increasing number of structures and machines because of their advantages over conventional materials such as steel or aluminum. However, sustained exposure to seemingly nominal service conditions can act to degr...

The magnetoelectric response of magnetostrictive/piezoelectric laminate composites has been investigated. Based on the piezoelectric and piezomagnetic constitutive equations, and motion equation for the composite plate, the magnetoelectric equivalent circuit has been derived, and the magnetoelectric coefficients predicted. Prototype devices of, as an application example, Terfenol-D/PZT composit...
