Computational mechanics
In a paper for nonlinear transient analysis of smart piezoelectric functionally graded material (FGM) plates, Wahab and his team presented a generalized shear deformation theory in combination with isogeometric (IGA) approach. Using the total Lagrange approach based on the von Kármán strains, a nonlinear transient formulation for plates is formed which includes thermo-piezoelectric effects, solved with the Newmark time integration scheme while the electrical potential through the thickness of each piezoelectric layer is assumed to be linear. According to the Mori-Tanaka schemes and the rule of mixture, the material properties vary through the thickness of FGM. To demonstrate the effectiveness of the proposed method, various numerical examples were presented. Using a novel numerical approach based on Isogeometric Analysis (IGA) and Higher order Shear Deformation Theory (HSDT), static, free vibration and dynamic control of piezoelectric composite plates integrated with sensors and actuators was investigated. The formulation fulfilled the high-continuity generalized displacements and the numerical studies showed good performance of the method used. Another study explored a new simple fur-unknown shear and normal deformation theory (sSNDT) for static, dynamic and buckling analyses of functionally graded material (FGM) isotropic and sandwich plates and in the relation between pain and stress, the fully three-dimensional material matrix is used. Through the Galerkin weak form, the discrete system of equations is derived and isogeometirc analysis (IGA) is used to numerically solve it. This required the C1-continuity of the displacement field and the condition is easily satisfied by the NURBS basis functions in IGA. Many examples are shown to illustrate the efficiency of the method used. To study the size dependent analysis of functionally graded carbon nano-reinforced composite (FG-CNTRC) nanoplates, a computational formulation was used based on IGA and generalized higher-order shear deformation theory (GHSDT). When compared to the other available numerical approaches used, the numerical results from this study prove high accuracy and reliability of this particular method. In another paper studying the size-dependent geometrically nonlinear transient analysis of functionally graded material (FGM) nanoplates, IGA integrated with high-order shear deformation theory (HSDT) was used. Wahab and his team investigated the effect of the resulting nonlocal approach on the behaviours of the FGM nanoplates with several volume fracture exponents and performed several numerical results to prove the reliability of the method used.

Fatigue of materials
Wahab and co-workers proposed and compared different techniques to derive dynamic bending stiffness of the experimentally determined modal characteristics of a reinforced concrete beam. As a result of the cracking of the reinforced concrete, there is degradation stiffness which provides information the severity and location of the damage that has taken place. They investigated the effect on the fatigue behaviour of CFRP/epoxy lap- strap joints by the test environment and pre-conditioning and it was found that the there was no significant variation observed in the fatigue resistance of the lap-strap until the glass transition temperature, Tg was approached, which is when a significant reduction in the fatigue threshold load could be seen. There is also a considerable reduction in the Tg of the adhesive because of the absorbed moisture and the locus of failure was observed to be highly temperature dependent. Another outcome was that the crack grew along the lap-strap joint, and the resolution of the forces at the crack tip had the tendency to force it into the strap adherend, possibly resulting in complex mixed mode fracture surfaces. In a paper, Wahab presented a literature review of articles published in the Web of Science from 1975 to 2011 on fatigue in adhesively bonded joints. There are about 222 cited articles reviewed and presented and the paper is concluded with highlighting topics important for future research.

Damage assessment
Wahab studied the effect of temperature variations on modal parameters recorded at two different times in a prestressed concrete highway bridge. To excite the bridge, a drop weight and ambient vibration were used and to support and verify the dynamic measurements, a finite element model was developed. The effect of the resulting changes in temperature were analysed and interpreted on the structure's natural frequencies. In an investigation of the long-term durability of adhesively bonded aluminium, composite and dissimilar substrate joints exposed to humid environments, the failure of the joints was modelled with a cohesive zone model (CZM) approach. In the dissimilar substrate joints, large residual stresses were induced because of the mismatch of coefficients of expansion of the substrates. The residual strength of the double lap joints was overestimated due to the predicted degradation which was possibly because of residual stress-enhanced degradation mechanism.

Islamic studies
Besides Wahab's research in engineering, he has conducted research in the Islamic religion. Over the past 15 years, he has been an Associate Imam and has also delivered Friday Ceremony speeches and Islamic talks in many mosques in the UK and Belgium. Wahab also authored the book Logic and Islam Part I: Faith issues: Answers to current questions. He authored a second book in this area Logic and Islam Part II: Scientific issues in 2020.
