Presentation / Conference
Alexandrou, A., Fotouhi, S., Nelson, J., & Cochran, S. (2023, November). Non-contact characterisation of piezoelectric materials. Poster presented at Electroceramics for End Users XII (ECEUXII), Glagow, UK

Piezoelectric materials play a key role in various technological applications owing to their unique elastic-piezoelectric-dielectric (EPD) properties, often represented in matrix form. Traditional methods for obtaining these properties, as defined by... Read More about Non-contact characterisation of piezoelectric materials.

Detection of barely visible impact damage in polymeric laminated composites using a biomimetic tactile whisker (2021)
Journal Article
Fotouhi, S., Khayatzadeh, S., Pui, W. X., Damghani, M., Bodaghi, M., & Fotouhi, M. (2021). Detection of barely visible impact damage in polymeric laminated composites using a biomimetic tactile whisker. Polymers, 13(20), Article 3587. https://doi.org/10.3390/polym13203587

This is a novel investigation on the possibility of detecting barely visible impact damage (BVID) in composite materials by whisking across the surface via tactile whisker sensors that resemble rats' whiskers. A series of drop tower low-velocity impa... Read More about Detection of barely visible impact damage in polymeric laminated composites using a biomimetic tactile whisker.

A comparative study on glass and carbon fibre reinforced laminated composites in scaled quasi-static indentation tests (2020)
Journal Article
Fotouhi, M., Damghani, M., Leong, M. C., Fotouhi, S., Jalalvand, M., & Wisnom, M. R. (2020). A comparative study on glass and carbon fibre reinforced laminated composites in scaled quasi-static indentation tests. Composite Structures, 245, Article 112327. https://doi.org/10.1016/j.compstruct.2020.112327

This paper investigates the effect of fibre properties of composite structures on the mechanical performance and formation of low-velocity impact damage. Quasi-static indentation tests were conducted on a comprehensive set of scaled Quasi Isotropic (...

Investigating polyethersulfone interleaved Glass/Carbon hybrid composite under impact and its comparison with GLARE (2019)
Journal Article
Fotouhi, S., Clamp, J., Bolouri, A., Pozegic, T. R., & Fotouhi, M. (2019). Investigating polyethersulfone interleaved Glass/Carbon hybrid composite under impact and its comparison with GLARE. Composite Structures, 226, 111268. https://doi.org/10.1016/j.compstruct.2019.111268

A tough polyethersulfone (PES) membrane was utilized as a novel reinforcement to improve impact performance of a carbon/glass hybrid composite. The hybrid composite was made of a glass fibre/epoxy block that was sandwiched between two carbon fibre/ep...
