Introduction:

Dr Chew Youxiang joined SIMTech in 2015 and has worked in the area of laser materials processing and friction stir welding. Dr Chew has experience in both experimental process development and numerical modelling of Laser aided additive manufacturing (LAAM) processes. He has continuously worked in extending the capability of using LAAM for 3D additive manufacturing applications both in terms and of scale and complexities of the components built. He also has research interest in microstructure simulation to correlate LAAM process parameters with mechanical properties of built parts. 

Research Interest:
  • Process development, deposition algorithm and strategies for fabrication of large 3D structure with overhang sections using LAAM.
  • Coupled thermal-fluid dynamics and residual stress simulation in LAAM.
  • Microstructure simulation of LAAM parts.
  • Fatigue life prediction of parts fabricated using LAAM.
