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 (2024)
Presentation / Conference Contribution

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...
