Easy-dispersible poly(glycidyl phenyl ether)-functionalized graphene sheets obtained by reaction of "living'' anionic polymer chains
(Royal Society of Chemistry, 2012)Excellent dispersion of functionalized graphene (FG) sheets in polystyrene was achieved relying on the reaction of “living” poly(glycidyl phenyl ether) chains onto graphene sheets. The physical aging of polystyrene was ... -
Simulation of distortion due to machining of thin-walled components
(Elsevier, 2013)The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ... -
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
(Elsevier, 2013)Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ... -
