The predictability of manufacturing process simulation is highly dependent on the accuracy
of the constitutive model to describe the mechanical behavior of the work material. The …

The fracture strain is known to be affected by the stress state and strain rate. To measure the
fracture strain over a wide range of stress triaxiality and strain rate, a rectangular hat-shaped …

Metal cutting, or simply machining, is one of the oldest processes for shaping components in
the manufacturing industry, which must fulfill not only the dimensional and geometrical …

Modeling the machining process by means of simulation techniques became more and
more popular within the last decades. The increasing use of simulation techniques can be …

The ductility of metallic materials is recognized to be significantly affected by stress state and
strain rate. However, systematic investigations on the impacts of stress state and strain rate …

This paper presents a semi-analytic rigid/plastic solution for the expansion/contraction of a
hollow sphere at large strains. The yield stress depends on the equivalent strain rate and the …

A thorough control of the machining operations is essential to ensure the successful post-
processing of additively manufactured components, which can be assessed through …

The scientific goal of the present work was to model the workpiece material behavior of
steels in the metal cutting process depending on the occurring thermo-mechanical loads …

This paper deals with the determination of the constitutive model coefficients used in
machining simulations. An optimization-based procedure is developed and applied to …

Titanium alloys are difficult-to-machine materials due to their complex mechanical and
thermophysical properties. An essential factor in ensuring the quality of the machined …
