This research aims to numerically simulate the performance of the tested PC utility poles using Applied Element Method (AEM) and Finite Element Method (FEM). The simulation results demonstrate that both AEM and FEM effectively reproduce the load-displacement relationship observed in the test. Additionally, this study discusses the material models employed in simulations, considering the limitations inherent in numerical modeling.

This study focuses on experimental testing and subsequent numerical analysis of impacted and pre-loaded composite coupons and bonded composite scarf joints under varying impact conditions. A methodology will be developed for the numerical modelling of preloaded impact tests to enable capture of critical failure modes and ultimate failure. The main aim is to validate a modelling strategy that will provide accurate failure characterisation of the tested joints using numerical analysis.

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

Doctoral thesis of Philosophy: Modelling of inhomogeneous magnetic fields in electromagnetic devices
This thesis derives closed form equations to describe electromagnetic device characteristics for a toroid, solenoid and a case study induction machine. By considering stored magnetic field energy, this approach allows the relationship between electrical, magnetic and kinetic energy to be quantified and analyzed in ways that allows improved accuracy compared with conventional magnetic circuit modeling methods. This thesis also provides insights into how geometric parameters impact energy transfer and operational characteristics of electromagnetic devices.
