Background

Upon receiving his Bachelor's in Mechanical Engineering from NEDUET Karachi in 2002, he joined Technology Promotion Internationals (Head Quarter: Maryland USA) for more than 3 years in the capacity of a Research Engineer. In these years, he was involved in fault diagnosis of defence applications mainly funded by General Dynamics including US Marines Expeditionary Fighting Vehicle (EFV) and Medium Tactical Vehicle Replacement (MTVR). In 2006, he went to The University of Manchester for his master's leading to doctoral studies and completed his PhD in 2008 with more than 12 publications and 2 patent applications in the area of fatigue diagnosis of gear assemblies. Later, he joined the University of Hertfordshire as a post-doctoral research associate in 2009 for two years. Where he worked on a UK MOD project related to aerospace transmission fatigue diagnosis and partnered with the University of Manchester, the University of Warwick and QinetiQ, he briefly taught Mechanical Engineering at Universiti Teknologi Petronas (Malaysia) as a lecturer in 2011 and the same year he then joined National University of Sciences and Technology (NUST) Pakistan as an Assistant Professor. At NUST, he established a Root Cause Failure Analysis (RCFA) centre and being the Head of the Postgraduate Programme started a new Master's in Computational Mechanics.

Dr Khan has experience in teaching UG and PG courses at leading universities in the UK, Malaysia, the Kingdom of Saudi Arabia, and Pakistan. He received an 'Outstanding contribution' award from the School of Aerospace, Transport and Manufacturing at 果酱视频官网 in 2020 and was nominated in the categories of best teacher and supervisor. The MSc in Maintenance Engineering and Asset Management (MEAM) was written, approved and launched under the leadership of Dr Khan as Course Director at Cranfield. The course has attracted both fresh graduates and professionals from the industry. National and International Companies including Boeing, BAE systems, Network Rail, MOD UK, MOD Turkey, Garuda Indonesia Airways, Pertokimia Gresik Indonesia, Shell Nigeria and OQ Oman have sent their employees for the course in the last two years.

He has been involved in industrial and academic research for the last 22 years. He has successfully supervised 18 PhD, 75 MSc and 100+ Undergraduate students. His focused areas of research interest are: Crack propagation in metallic, 3D printed polymeric structures and machine components, Experimental evaluation of damage and prediction of useful life, Non-destructive testing methodologies and Tribological phenomenon in mechanical contacts. Dr Khan is a Chartered Engineer (CEng) and a Fellow of the Institute of Mechanical Engineers (IMechE) UK.

Research opportunities

Dr Khan is currently working with his research group including 1 Post-Doctoral Fellow, 21 Doctoral and 6 MSc students in the following five areas of research:

i.Structural health monitoring

ii.Wear and Noise interdependency

iii.Smart-printed surfaces and materials

iv.Environmentally assisted material degradation

v.Asset maintenance and health assessment

Corresponding laboratories in all the above areas have been established at Cranfield since 2017. Students with self-funding sponsorships and industrial clients are welcome to contact us for details about the ongoing research in the above areas.

Current activities

1- Vibration response and damage propagation in mechanical structures. Sponsored by UTC Aerospace System, Govt of KSA and Libyan Govt

This project involves analysis of crack propagation in metallic, 3D printed polymeric and concrete structures under resonant load and elevated temperature. The aim of the analysis is to develop a mathematical relationship that can estimate the crack propagation, fatigue and fracture life of material with reliability.

2- Modeling damage by using dynamic response in complex geometrical structures. Sponsored by Cummins UK

Cummins UK is a specialist in making battery packs for electric vehicles. However, the damage in these battery packs is still an issue to diagnose due to composite shapes and complex geometries of constituent elements. Cranfield is working with Cummins to establish the theoretical foundation which can allow an analysis of the dynamic response available in a multicomponent complex geometrical structure under normal working conditions.

3- Sub-surface damage quantification. Sponsored by PTDF Nigeria and Libyan Govt

This work focuses on the damage quantification of critical soil-embedded structures. Ultrasonic damage detection methodology is currently being proposed. A model is under development which can allow using the guided wave formulation with a reduced reflection factor and reliable prediction.

4- Condition monitoring of misaligned gear systems via vibration and acoustics measurement techniques. Sponsored by PTDF Nigeria and Govt of KSA.

The scope of this project is to investigate the behaviour of gear failures under shafts' misaligned loads. Specifically focuses on fatigue failure of gears and its effects on vibration and acoustic spectrum.

5- Surface wear prediction with airborne noise. Sponsored by Libyan Govt

The scope of this project is to model the interdependencies between surface wear of mechanical contacts with its inevitable generated noise. The research is currently being investigated on the mentioned interdependencies at the aspherical level of mechanical contacts in dry and lubrication conditions.

6- Model the material damage parameters with pipe-line leakage rate (Sponsored by Libyan Govt)

The scope of this project is to investigate the key damage mechanisms of metallic pipelines and their relationship with leakage initiation and rate. This research will model the leakage rate with environmental-assisted damage parameters as an input.
