Abstract: Structural Health Monitoring (SHM) is a remote non-destructive inspection technique that enables instantaneous maintenance request when the system’s health fall below a predefined level of confidence. The concept of SHM is to continuously monitor the state of a structure with permanently installed sensors and allow for condition-based maintenance (CBM) where maintenance action is carried out only when a threat to the structures’ integrity is detected. SHM has been recognized as an attractive solution for the life management of engineering structures. SHM systems consist of various sensors types integrated within the structure to record its response to external events under various environmental and operation conditions.

This talk aims to introduce the concept of SHM, mainly guided wave based methodology with the particular focus on damage detection and characterization in composite structures. Some of the existing challenges and their proposed solutions for the uptake of the SHM systems in real structures under operation will also be emphasised.

Biography: Dr Zahra Sharif Khodaei is an Associate Professor in Structural Integrity in the Department of Aeronautics, Imperial College London. She is the co-founder of the Structural Integrity and Health Monitoring (SI&HM) group. Her main area of expertise is in the field of Structural Health Monitoring (SHM), both numerical and experimental research in passive (impact detection & classification) and active sensing (damage detection & characterization) of smart structures. She has developed different SHM systems using piezoelectric, fibre optic and novel printed sensor technologies as well as methodologies for diagnosis & prognosis of composite structures under environmental and operational conditions. The developments have been carried out within several collaborative projects involving UK industries and academia, EU projects (SHERLOC CleanSky II, €10M) and more recently European Space Agency (ESA) for space application. She is a member of the steering committee of CleanSky II and a Fellow of Royal Aeronautical society and Women’s Engineering Society. As of 2022, Zahra will be appointed as a Visiting Professor at the Czech Technical University in Prague.
