Application of low frequency guided waves to delamination detection in large composite structures: a numerical study

Paper in proceeding, 2020

The aim of the current work is to identify the challenges in computational modelling of ultrasonic guided
wave propagation in large structures and developing methods to overcome them. The work includes
investigating the application of GW in composite laminates and sandwich materials with the aim of
delamination detection. Moreover, phased array systems are introduced as a method of overcoming the
negative effect of high damping properties in such structures. Propagation of GW in a wind turbine blade
is studied as an example of large structure with the aim of defect detection. Results that show GW can
be used as a potential tool for structural health monitoring of wind turbine blades.
