Modelling of Stress Evolution and Its Effect on Formability in Tension Under Cyclic Bending Plus Compression
Presentation / Conference Contribution
Peng, W., & Ou, H. (2023, September). Modelling of Stress Evolution and Its Effect on Formability in Tension Under Cyclic Bending Plus Compression. Presented at 14th International Conference on the Technology of Plasticity, Cannes, France

Single point incremental forming (SPIF) and Double-sided incremental forming (DSIF) are two main variants of incremental sheet forming (ISF) processes. Tension under cyclic bending (TCB) have been developed as a means for experimental evaluation and...

Experimental testing and numerical modelling of ductile fracture of PEEK in incremental sheet forming process
Presentation / Conference Contribution
Gatea, S., & Ou, H. Experimental testing and numerical modelling of ductile fracture of PEEK in incremental sheet forming process. Presented at 27th International ESAFORM Conference on Material Forming (ESAFORM 2024), Toulouse, France

This research investigates the use of Hooputra-based damage model to predict fracture of polyether-ether-ketone (PEEK) material and its application to single point incremental forming (SPIF) process under different conditions. Flat PEEK sheets are us... Read More about Experimental testing and numerical modelling of ductile fracture of PEEK in incremental sheet forming process.

Spindle speed effect on the ISF processing of materials with different thermal conductivities
Presentation / Conference Contribution
Qin, Z., Gatea, S., & Ou, H. Spindle speed effect on the ISF processing of materials with different thermal conductivities. Presented at 27th International ESAFORM Conference on Material Forming (ESAFORM 2024), Toulouse, France

Incremental sheet forming (ISF) is an advanced forming technology with high flexibility and excellent adaptability. However, conventional ISF encounters challenges in processing of hard-to-deformed materials at room temperature. To address this probl...
