Composite materials/structures are advancing in product efficiency, cost-effectiveness and
the development of superior specific properties. There are increasing demands in their …

Shearography is a full-field speckle interferometric technique used to determine surface
displacement derivatives. For an interferometric technique, shearography is particularly …

Graphene and its derivatives have become the most explored materials since Novoselov
and Geim (Nobel Prize winners for Physics in 2010) achieved its isolation in 2004. The …

Composite materials have gained popularity in automotive industries due to its lightweight
potential, good damping behaviour as well as high strength and stiffness properties. Based …

Optical fibre sensors are being investigated since many years as candidates of choice for
supporting structural health monitoring (SHM) in aerospace applications. Fibre Bragg …

This paper presents the activities in the field of shearography in chronological order and
highlights the great potential of this holographic measurement technology. After a brief …

In recent years, Levy flight (LF) is increasingly being employed as search mechanism in
metaheuristics optimization algorithms (MOA) to solve complex real world problems. LF …

Material failure may occur in a variety of situations dependent on stress conditions,
temperature, and internal or external load conditions. Many of the latest engineered …

This paper compares two fibre optic sensing techniques for vibration characterisation:(a)
optical fibre Bragg grating (FBG) strain gauges and (b) a novel direct fibre optic shape …

The fiber Bragg grating (FBG) sensors are widely used in strain measurement. However, the
current FBG sensors are not sensitive enough to monitor the micro-strain. In order to provide …
