Disc brakes are a crucial part of a vehicle. They slow or stop a vehicle by converting the kinetic energy into heat. This heat causes the disc surface temperature to rise in a short period of time. Due to the severe working conditions during operation, cracks develop on the friction surface. Simulation of residual stresses causing the initiation of these cracks with reasonable computational resources was one of the main goals of Asim’s research as a PhD researcher.
The residual stresses in a part built using an additive manufacturing process can lead to part distortion, loss of geometric tolerance and have detrimental effects on the fatigue performance. Due to the complex thermal phenomenon which occurs during the additive manufacturing process, understanding the relationship between processing parameters and final part properties is a challenging task. Asim’s interest lies in the investigation of how the residual stresses affect the final part geometry and how to improve the process parameters for an ideal stress-free build of a part.
