Journal Article
Gatea, S., Xu, D., Ou, H., & McCartney, G. (in press). Evaluation of formability and fracture of pure titanium in incremental sheet forming. International Journal of Advanced Manufacturing Technology, https://doi.org/10.1007/s00170-017-1195-z

A forming limit diagram (FLD) is commonly used as a useful means for characterizing the formability of sheet metal forming processes. In this study, the Nakajima test was used to construct the forming limit curve at necking (FLCN) and fracture (FLCF)...

Understanding the deformation and failure mechanisms in single point incremental forming (SPIF) is of great importance for achieving improved formability. Furthermore, there will be added benefits for more in depth evaluation of the effect of localis...

Hot tensile fracture characteristics and constitutive modelling of polyether-ether-ketone (PEEK) (2017)
Journal Article
Chen, F., Ou, H., Gatea, S., & Long, H. (2017). Hot tensile fracture characteristics and constitutive modelling of polyether-ether-ketone (PEEK). Polymer Testing, 63, https://doi.org/10.1016/j.polymertesting.2017.07.032

The effects of strain rate and deformation temperature on the deformation behaviors of polyether-ether-ketone (PEEK) were studied by uniaxial tensile tests with the temperature range of 23–150 °C and strain rate of 0.01–1 s−1. The effects of deformat... Read More about Hot tensile fracture characteristics and constitutive modelling of polyether-ether-ketone (PEEK).

Evaluation of deformation stability and fracture mechanism in incremental sheet forming (2017)
Journal Article

Incremental sheet forming (ISF) is a flexible process for rapid manufacturing of complex sheet metal parts. An advantage of ISF is the improved formability than traditional sheet forming processes such as stamping. A number of fundamental studies hav...
