Research interests
Nonlinear Structural Stability
Professor Wadee is looking to recruit new PhD students in the field of nonlinear structural mechanics, in particular he is particularly focusing on metamaterials, thin-walled structures and cable stiffened structures.
My research group's work has been profiled on the ASCE Engineering Mechanics Institute website (Link). We have investigated the following aspects of nonlinear structural mechanics:
- Nonlinear mechanical systems
- Geometric approaches to mechanical modelling
- Coupled instabilities in optimized structures
- Sandwich structures
- Composite and layered materials
- Thin-walled structural components
- Prestressed steel structures
- Tubular structures
On-going research projects
- Buckling and delamination of sandwich structure systems
- Kink banding in layered structures and materials
- Interactive buckling of thin-walled structural components
- Post-buckling of prestressed stayed columns
- Delamination and kink banding in composite laminates
- Localized buckling in elastic tubes
Research lineage
My current Erdös number is 4.
