Abstract 3D printing is changing the way we conceive, design, and build 3D objects in
mechanical, biomedical, aerospace, construction, automotive and maritime industries. In the …

In order to manage the processing of polymers one needs to understand and be able to
quantify the rheological phenomena occurring in complex flows of viscoelastic materials …

Thermoplastic vulcanizates (TPVs) are a special class of polymer blends comprised of a
thermoplastic polypropylene (PP) matrix and a dynamically vulcanized ethylene propylene …

The performance of roadheaders in cutting hard rocks can be improved using high-pressure
waterjet technology. The optimum position of waterjet nozzles and the threshold pressure in …

We report the design of a microcapillary rheometer (μCR) that allows to perform experiments
rapidly and in a broad range of shear rates (ie, from 0.1 to 1000 s− 1), using small amounts …

The study presents the results of rheological tests of wood polymer composites (WPC) on a
polypropylene matrix. The influence of the filler on the additional pressure losses as a result …

The excess pressure losses due to end effects (mainly entrance) in the capillary flow of
several types of polyethylenes were studied both experimentally and numerically under slip …

The capillary flow of a commercial low‐density polyethylene (LDPE) melt was studied both
experimentally and numerically. The excess pressure drop due to entry (Bagley correction) …

Rheological properties related to the extrusion of polyolefins are the shear viscosity, the
elongational viscosity, the slip velocity and their temperature-and pressure-dependencies …

In this paper visualisation and direct velocity profile measurement experiments for a
branched polypropylene melt in a 10: 1 axisymmetric contraction demonstrate the onset of …
