   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; objective strain rates; hypoelastic-inelastic consitutive modelling; Johnson-Cook plasticity;

   Abstract : incorporation of new design materials – e.g. in order to promote lightweight design – oftenleading to significant changes in manufacturing conditions, which can be assessed in anefficient way by simulation rather than more expensive testing. READ MORE

4. 2. Modeling of cast iron materials related to machining

   Author : Goran Ljustina; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; Microstructure; Fracture; Johnson Cook plasticity;

   Abstract : A microstructure level simulation model of cast iron machining based on micrograph image analysis has been developed. The simulation tool has been developed for theorthogonal machining process involving 2D representations of a range of cast iron microstructures. READ MORE
