BackgroundThe academic path for Dr Dayyani is originated at Isfahan University of Technology, Iran; where he passed his BSc and MSc. During these years, he practiced a wide range of courses in mechanical engineering and published three journal papers on buckling analysis of point-restrained triangular plates, experimental analysis and nonlinear finite element simulation of corrugated composite structures.
Graduating from MSc, he was appointed as a full time research assistant and simultaneously a full time PhD student on "optimization of multi-scale structures with applications to morphing aircraft" project, at Swansea University. His contribution in this project was to design a composite corrugated skin with extreme anisotropic behavior. The morphing skin required high stiffness to withstand the external aerodynamic loads while flexibility to enable the shape changes. Considering the multi-scale framework of this project he investigated homogenization techniques, super element modelling, multi-objective optimization, design and manufacturing procedures for composite corrugated skins with regards to practical constraints. The results of these investigations are published in prestigious international journals in the field of Composites, Solids and Structures.
Graduating from PhD, he was appointed as a lecturer at Coventry University. His role in this post was mainly research for the design of lightweight composite structures for carbon efficient vehicles. In this regard, He was a member of ''Research Center for Transportation and Mobility'' at Coventry University interacting with Jaguar Land Rover.
Current activitiesDr Dayyani’s research interests lie in the development of novel structural characteristics for multidisciplinary problems in aerospace engineering, e.g. lightweight structures with extreme anisotropic behaviour. This includes a broad range of work on Morphing Skins and Adaptive Structures capable of large scale geometry changes. He uses a variety of analytical, numerical, and experimental techniques to develop a problem from low fidelity analysis in concept level to high-fidelity investigation in modelling validation. His main research theme includes:
- Homogenization Techniques, Super Element Modelling
- Design and Multi-objective Optimization
- Finite Element Simulation
- Stability and Buckling Analysis
- Experimental Analysis of Composite Structures
