Carry out 3D bladed disc analysis on gas turbine compressor components using ABAQUS or MSC NASTRAN. Modelling only the sector model using cyclic symmetry. Modelling contacts between the blade and disc interface using ABAQUS contact capability.
• Vibration analysis – Carry out normal mode analysis for various models including 3D bladed disc sector model using ABAQUS, MSC NASTRAN or SC03. For gas turbine rotor, checking for interference from different engine order as well as looking at the different mode shapes at different nodal diameters.
• Steady state heat transfer – Carry out analysis to obtain temperatures required for stress and vibration analysis. Developed the methodology of mapping 2D temperature results from ANSYS to ABAQUS 3D model. Also developed the methodology of mapping temperature results from ANSYS to SC03 through the use of ITEM file.
• Meshing – Using MSC PATRAN and Hypermesh to generate finite element mesh to the required stress accuracy on complex geometry.
• Secondment to Airbus UK, Filton – Work in the static stress checkstress department, running FESPS, Comphilo, Airbus Collection, and SIMPLOT to identify and to understand stress exceedences in wing box FEM. Carry out check on some areas of the wing box FEM, discovering anomalies and reporting it. Prepared documents to other department to carry out changes required for checkstress activities. Learnt the principles underlying the wing design and analysis procedures used.

• Derived composite version (full anisotropic) of various linear shell theories (Donnell, Loo, Morley, Flügge, Sanders), specifically for axial compression buckling, using MAPLE due to its powerful symbolic feature. Calculated analytical buckling load and mode shape using MAPLE and Excel VBA.
• Reduced the buckling equation into simple equation in non-dimensional form for design purpose. Validated equation using ABAQUS linear bifurcation/eigenvalue analysis.
• Studied the effects of different couplings on shell buckling.
• Studied the effects of length, radius and thickness to tube buckling with interaction of different couplings, giving definition of short, intermediate and long tube. Utilised parametric studies feature of ABAQUS to obtain thousands of dataset for analysis.
• Optimisation of composite lay-up for axial buckling (considering local and global buckling) using Excel VBA as well as Compshell, a program developed using Delphi by myself.

• Responsible for delivering structure laboratory (lightweight aircraft engine frame forces and bending moment) to 2nd year Aeronautical Engineering students. Marking student laboratory reports.
• Tutorial assistant of Fluids and Thermodynamics, helping students in tackling these questions.
