Dr Hafiz Ali

Research summary

Hafiz is currently working on an EU funded consortium involving developing nonlinear ultrasonic techniques to allow the determination of bond strength in composite structures. The key research challenges are interpreting the complex nature of the transmitted nonlinear signal and optimizing the operating point selection for thin specimens.

Main challenges include:

• Experimental demonstration of various nonlinear ultrasonic techniques in thin specimens
• Development of models to allow easy selection of a guided wave operating point for inspection of thin components
• Usage of nonlinear guided wave inspection techniques to investigate the levels of nonlinearity present in thin composite specimens of varying bond strength.

Biography

Hafiz Ali completed his BSc with Honours in Indurstrial and Manufacturing Engineering (IME) from University of Engineering and Technology(UET) Lahore, Pakistan in 2004. He then secured MSc with Merit in Advance Manufacturing Management and Technology (AMMT) from University of Surrey, UK in 2006. Hafiz, during his PhD from University of Surrey, designed and manufactured a novel loading configuration to investigate and characterise the behaviour of the extremely important commercial polymer, FM-73M, under mixed-mode loading –applied both quasi-statically and cyclically. Under quasi-static testing, the strain energy release rate components at fracture were presented in a conventional G_I (mode I ...
