Dynamical structure of entangled polymers simulated under shear flow

, 2018
The non-linear response of entangled polymers to shear flow is complicated. Its current understanding is framed mainly as a rheological description in terms of the complex viscosity.

Cutting forces prediction: The experimental identification of orthogonal cutting coefficients [PDF]

FME Transactions, 2017
In this paper the cutting coefficients were identified applying the orthogonal cutting mechanics, which are used in the cutting forces and torque prediction. The experiments were performed for material combination of the workpiece (16MnCr5) and tool (HSS-
