Research

Zahur’s research expertise lies at the intersection of advanced numerical methods such as finite element and meshless and applied solid mechanics, with a particular focus on the analysis and optimisation of Fibre Reinforced Polymer (FRP) composite materials and structures.

During his PhD at Durham University, he developed coupled finite element-meshless methods for the solution of solid mechanics’ problems subjected to both material and geometrical nonlinearities. As a post-doc researcher at the University of Glasgow, he contributed to the development of advanced finite element software MOFEM (Mesh-Oriented Finite Element Method) for the prediction of long-term durability of FRP composite structures subjected to harsh hygro-thermal environmental conditions in addition to mechanical loading. As a part of this multi-university and multi-disciplinary project, he gained first-hand expertise in multi-scale and multi-physics (hygro-thermo-mechanical) modelling, elasto-plasticity, finite deformation/strain mechanics, damage mechanics, hierarchic basis functions, high-performance computing, stochastic multi-scale finite element method (SMFEM) and structural reliability. In addition, he also worked on the computational fracture mechanics to model crack propagation in nuclear reactors.

More recently, Zahur's research has focused on the computational modelling and assessing the impact damage in efoil-powered composite marine structures, and hybrid metal-composite laminates for bolted joints. He has also worked on the computational micromechanics and the application of Artificial Neural Networks (ANN) in the failure prediction of composite materials. Additionally, his work on the Finite Fracture Mechanics (FFM) aims to predict free-edge delamination in both monolithic and hybrid composite-metallic laminates under static and fatigue loading. His research also extends to topology optimisation of isotropic and composite structures, and energy absorption behaviour of 3D-printed fibre-reinforced hybrid structural metamaterials.

Teaching

At Durham University, Zahur currently (2024-25) teaches 3rd year Finite Element Methods and contributes to 2nd year design projects. Over the years, he has developed and delivered a wide range of courses, including dynamics, optimisation, topology optimisation, mechanics of fibre reinforced polymer composites, mechanics of materials, and programming with MATLAB and C++.
