Chinnapat Panwisawas BSc, PhD, CEng, FIMMM, FInstP, FIMechE -- Dr Panwisawas is currently Senior Lecturer (Associate Professor) in Materials and Solid Mechanics, School of Engineering and Materials Science, Queen Mary University of London (QMUL). Dr Chinnapat Panwisawas obtained his PhD in Metallurgy and Materials from University of Birmingham, UK (2013) and his BSc (First Class Honours) in Physics (Honours Programme) from Department of Physics, Chulalongkorn University in Thailand (2008). After the conferment of his PhD, Dr Panwisawas has joined Rolls-Royce University Technology Centre at University of Birmingham from June 2013 to May 2018 as Research Fellow. In June 2018, he has awarded EPSRC UKRI Innovation Fellowship and became Senior Fellow at Department of Materials University of Oxford. Before joining QMUL in July 2022, Dr Panwisawas was Associate Professor in Digital Manufacturing and Associate Director of NISCO UK Research Centre at School of Engineering, University of Leicester.

recrystallisation to occur. The influences of differential thermal contraction against the shell, specimen geometry and stress concentration factor are quantified. The model predicts that the induced strain in the metal increased with the ceramic shell thickness, and in some geometries, with the solidification height. Negligible plastic strains were predicted in a solid casting with no stress concentration features. However, as the geometry became more complex by reducing the casting cross-section, by the insertion of a core and introduction of stress concentration features, the induced plastic strains increased signfi?cantly. The predicted plastic strain for recrystallisation in a cored casting was in good agreement with experimental critical strain data. The model provides the foundation for a systems-based approach which enables recrystallisation to be predicted and thus avoided, prior to its occurrence in the foundry.
