Dr Chinnapat Panwisawas is a Research Fellow in School of Metallurgy and Materials. He obtained his PhD in Metallurgy and Materials from University of Birmingham, UK (2013) under the supervision of Professor Roger C. Reed, and his BSc (1st Class Honours) in Physics (Honours Programme) from Department of Physics, Chulalongkorn University, Thailand (2008). After the conferment of his PhD, Dr Panwisawas has joined the CASiM2 research group led by Professor Jeffery W. Brooks and Dr. Hector C. Basoalto of the University of Birmingham in June 2013.

Currently, his research interest focuses on multi-scale multi-physics approaches to modelling of liquid/solid reactions, particularly in fusion welding and additive manufacturing of high performance alloys (nickel-based superalloys and titanium alloys) within an integrated computational materials engineering (ICME) framework. Validatory studies with a variety of experimentation are used to verify the mathematical modellings.

Chinnapat Panwisawas received a BSc (1st class honours) in Physics (honours programme) at Department of Physics, Faculty of Science, Chulalongkorn University, Thailand in 2008. During his undergraduate study, Chinnapat has joined the Theoretical High-Energy Physics and Cosmology Group, Chulalongkorn University. His individual studies and undergraduate projects concentrated on non-linear dynamical system, fluid dynamics and turbulence theory.

Dorothy Hodgkin Postgraduate Award (DHPA) received from Rolls-Royce plc and Engineering and Physical Science Research Council (EPSRC) provided him a further study in pursuing his PhD under supervision of Professor Roger C. Reed (now at Departments of Engineering Science and Materials, University of Oxford). His PhD research topic concerned about recrystallisation during investment casting of single crystal superalloys. Computer simulation via finite element calculation along with sophisticated experimental validation, partly collaborated with University of Cambridge, has been carried out to predict plastic strain which was a driving force for recrystallisation. His PhD research has been assessed to meet Technology Readiness Level 6, at which the technology and innovation were ready to implementation, and he won The Anglo-Thai Society Educational Award for Excellence in Engineering 2012 as his PhD research provided an big impact to scientific community.

In June 2013, after his PhD has been awarded, he has joined the University of Birmingham as a research fellow working at the Centre for Advanced Simulation and Modelling (CASiM2). His research work focuses on establishment of an ICME methodology to predict microstructural variability induced by the liquid-solid reactions resulting from manufacturing process and to calculate the resulting location specific mechanical behaviour. Multiple physics principle has been used to construct a physics-based tool to better understand the materials properties.


Teaching Programmes

  • A tutor for the Fluid flow, thermodynamics and heat transfer course.


Materials science and physics of structural materials is of interest. Emphasis has been made on the design, mechanical behaviour and processing of these materials. Numerical and analytical analysis of these phenomena using both purpose built software and commercial codes has been used along with validatory studies using targeted experimentation. Damage accumulation due to the microstructural instabilities in these systems is of interest.

Currently, my research interest focuses on multi-scale, multi-physics approach to modelling of materials and processing using an integrated computational materials engineering (ICME) framework. Computational fluid dynamics (CFD) calculation, cellular automata (CA) finite element method along with micromechanics and macromechanics using dislocation density based crystal plasticity (CP) modelling have been used for integrated modelling of microstructure to determine the integrity of materials processing and manufacturing.
