Contact Dr Hessam Ghasemnejad

Areas of expertise


Dr Ghasemnejad joined Cranfield University in 2016 as a senior lecturer in structures in the centre for structures, assembly and automation; he is also the course director for the MSc Advanced Lightweight and Composite Structures course. Prior to joining Cranfield Dr Ghasemnejad was a senior lecturer in composite materials (2011-2016) and a lecturer in Engineering design (2009-2011) in the school of aerospace and aircraft engineering at Kingston University London. He also acts as Member of Engineering Council (Chartered Engineer), IMechE Academic Review Panel, Fellow of Higher Education Academy (FHEA), the EPSRC Associate Peer Review College, Editorial Board of Journals and Scientific Committees of International Conferences. He has secured industrial research and training grants from Innovate UK, DoD and SME partners on impact and crash analysis of advanced composite structures (Innovate UK - Design and Optimisation of CFRP Aircraft Structures, 2013, and Innovate UK - Development of a Novel, Affordable Neonate/Infant Transport Incubator, 2017).

Completed PhD Supervisions as Principal Supervisor:

1- Structural Integrity Enhancement of UAVs using 3D Printed Structures (2019).

2- Analytical Impact Analysis of Variable Curved Composite and Sandwich Panels (2017).

3- Optimisation of Failure Mechanisms in Crashworthiness of Multi-stitched Composite Tubular Absorbers (2017).

4- Analysis of the Effect of High Velocity Impact Damage on the Repairability of CFRP Composite Panels (2016).

5- Explicit Finite Element Analysis to Predict Impact Damage Response of Osteoporosis Hip Bone (2014).

6- Delamination Failure in Natural Stitched Composite Structures (2013).

Current activities

Dr Ghasemnejad's main research activities are focused on experimental, analytical and numerical aspects of stability and failure in composite structures under various loading conditions such as buckling, post-buckling, fatigue, impact damage, blast and crash. In his research, he has studied crashworthiness of aluminium and composite structures based large plastic deformation and fracture mechanisms under quasi-static and impact loading conditions. He investigated the interlaminar crack propagation in multi delamination modes and their effect on the progressive crushing process and specific energy absorption of composite structures. More recently he has developed a robust mathematical model to analyse the impact damage of doubly curved composite panels with variable stiffness. Adopting the mathematical-based approach in the study of transient dynamic behaviour provides significant contribution into the role of impact engineering in composite structures.

Dr Ghasemnejad is also involved in an £8.9m joint Innovate UK and Rolls-Royce funded program named 'Powerplant Integration with Platform Systems' (PIPS) with the structures work package which has a target of significant structural weight reduction in the wing, pylon and engine integration by systematic structural system design optimisation with extensive full scale experimental validation.
