Fuzzy logic based active vibration control using novel photostrictive composites

Although conventional actuators like piezoelectric and electrostrictive are efficient, but they required hard wiring, which contaminates the control signal and adds to the weight of the structure. The current study presents a wireless control strategy using photostrictive actuators. Owing to the fortunate combination of photovoltaic effect...

External surface cracked offshore pipes reinforced with composite repair system: A numerical analysis

This paper conducts a numerical analysis on the external surface cracked steel pipes reinforced with Composite Repair System. A three-dimensional finite element (FE) model is developed to calculate the Stress Intensity Factor (SIF) of the surface crack, and the crack growth process is evaluated by the Paris’ law. The effect of FRP-to-steel...

Coupled hygro-mechanical finite element method on determination of the interlaminar shear modulus of glass fiber-reinforced polymer laminates in bridge decks under hygrothermal aging effects

To investigate the mechanical degradation of the shear properties of glass fiber-reinforced polymer (GFRP) laminates in bridge decks under hygrothermal aging effects, short-beam shear tests were performed following the ASTM test standard (ASTM D790-10A). Based on the coupled hygro-mechanical finite element (FE) analysis method, an inverse...

An interface element for modelling the onset and growth of mixed-mode cracking in aluminium and fibre metal laminates

Stress distribution around a circular hole in a fibre metal laminate finite width plate specimen

The stress distribution in the vicinity of a notch is investigated as a first step towards a more fundamental understanding of the blunt notch behaviour of fibre metal laminates. The applicability of several analytical methodologies for determination of the stress distribution in the vicinity of a notch in a finite width plate is assessed in...
