1. Influence of Microstructure on Chip Formation - Machining Aero Engine Alloys
Sammanfattning : Aero engine materials such as nickel-iron and titanium based alloys are known to be very difficult to machine. They are also known to produce shear-localized chips; a type of chip which is associated with both an increase of the tool wear and the vibration levels during machining. LÄS MER
2. Non-local models in manufacturing simulations
Sammanfattning : Ductile fracture presents challenges with respect to material modelling andnumerical simulations of localization. The strain and damage localization maybe unwanted as it indicates a failure in the process or, as in the case ofmachining and cutting, a wanted phenomenon to be controlled. LÄS MER
