Laser-assisted turning (LAT) involves locally heating a rotating workpiece using a focused laser beam before the removal of material. A key aspect in optimising productivity with laser-assisted turning is understanding the thermal relationship between laser heating, the improved material removal rate, and machinability. Consequently , in this paper...
Mechanical drilling of carbon fibre-reinforced polymer (CFRP) composites is common in industrial applications , but suffers from extensive tool wear, fibre delamination and high tooling cost. This research shows that by using simultaneous laser and mechanical hybrid drilling, tool life can be increased by 88% and a 36% reduction in unit process Sco...
Al-SiC metal matrix composites (MMCs) are promising materials for aerospace and electronic packaging applications. However, machining of Al-SiC MMC is very challenging, often resulting in surface scratches by the hard SiC particles and extensive tool wear. Recent approaches of laser assisted machining using low cutting speeds and low laser power de...

Question (1)
Hi. Dear any Abaqus experts who have modelled composites machining, could you kindly help me on this issue?
The elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively. It can be seen that the matrix overlaps with one of the circular particles, which causes this issue. In other cases, the matrix overlaps other areas of the matrix it self. Do you happen to know why and how to solve this issue? Thank you.
