Acoustic emission-based failure detection and monitoring of composite panels for wind turbine applications


Project Description

Robert Gordon University, through the School of Engineering is offering a PhD studentship with tuition fees funded for Home/EU or International applicants.

This is a fees-only funded PhD studentship provided by the School of Engineering and interested candidates will have to secure their own financial support to upkeep their living costs.

The use of composite materials has significantly increased over the past few decades. Given the heterogenous nature of composites and the existence of multiple modes of failure, it is crucial to understand the failure phenomena to predict the remaining useful life of certain critical components such as wind turbine blades. This helps in decreasing the operational and maintenance costs. The use of Machine Learning (ML) has gained significant traction in all fields related to engineering to enable predictive maintenance. The suitability of this technique for composite failure prediction shall be investigated in this project.

The objective of the study is to quantitatively characterise the different failure phenomena in composites using an acoustic emission based on-line monitoring system. The effect of embedding the sensor within the composite during fabrication on the failure detection shall be understood and compared with a surface mounted case. Experimental and numerical simulation methods will be used to test the composite specimens in various loading conditions. The AE feature database corresponding to the composite failure modes shall then be used to create a failure prediction model using machine learning (Artificial Neural Networks) techniques. This study contributes towards building a “Digital Twin” of a wind turbine.

Applications should be emailed to Dr Anil Prathuru at . The applications should consist of a covering letter or personal statement of interest, and a CV.

Deadline for receipt of applications is 15th April 2020.

It is expected that candidates are available to register and commence study in October 2020.
