Constitutive modelling of hot deformation behaviour of metallic materials (2021)
Journal Article
Zhu, H., & Ou, H. (2022). Constitutive modelling of hot deformation behaviour of metallic materials. Materials Science and Engineering: A, 832, Article 142473. https://doi.org/10.1016/j.msea.2021.142473

The complexity of hot deformation behaviours of metallic materials is acknowledged in decades of study. The present work uses a new constitutive model by Zhu-Ou-Popov (ZOP model) and its modifications to predict the hot deformation behaviours of meta...

PEEK based cranial reconstruction using thermal assisted incremental sheet forming (2021)
Journal Article
Chen, L.-F., Chen, F., Gatea, S., & Ou, H. (2022). PEEK based cranial reconstruction using thermal assisted incremental sheet forming. Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 236(6-7), 997-1004. https://doi.org/10.1177/09544054211045904

Compared to conventional sheet forming operations, incremental sheet forming (ISF) is a flexible forming technique that can achieve higher formability in terms of localized deformation. Due to excellent mechanical properties and X-ray penetration, po... Read More about PEEK based cranial reconstruction using thermal assisted incremental sheet forming.

Multiscale modeling of discontinuous dynamic recrystallization during hot working by coupling multilevel cellular automaton and finite element method. International Journal of Plasticity, 145, Article 103064. https://doi.org/10.1016/j.ijplas.2021.103064

Discontinuous dynamic recrystallization (dDRX) is considered an effective way to obtain fine grain microstructures during hot working of materials with low-to-medium stacking fault energy (SFE). However, to date, investigation and modeling of dDRX in...
