To describe the macroscopic rheological behavior of thixotropic elasto-visco-plastic (TEVP)
materials, phenomena that take place in their microstructure must be accounted for. To this …

Digital twins have emerged as a key technology for optimizing the performance of
engineering products and systems. High-fidelity numerical simulations constitute the …

Different design of experiments (DoE) strategies for generation of injection molding process
data and later usage as training database, eg for an artificial neural network substitute …

The mixture of metal powder and a viscous polymeric binder (often referred to as feedstock)
is commonly used for Metal Injection Moulding (MIM) applications. Recently, the interest …

The appearance of surface distortions on polymer melt extrudates, often referred to as
sharkskin instability, is a long-standing problem. We report results of a simple physical …

The recently proposed finite element (FE) formulation for viscoelastic flows that allows the
use of equal order linear interpolants for all variables and simultaneously does not suffer …

The flow inside a fluid damper where a piston reciprocates sinusoidally inside an outer
casing containing high-viscosity silicone oil is simulated using a finite volume method, at …

A numerical model is developed to examine the die swell for fiber suspensions, which
occurs in 3D printing extrusion processes. More specifically, it focuses on the fiber …

The characteristic time periodicity τ* and the spatial characteristic wavelength λ of extrusion
flow instabilities of a linear and a branched commercial polyethylene (PE) are characterized …

Metal injection molding (MIM) feedstocks are mixtures made of a solid metal powder and a
viscous polymeric binder. Vertical extrusion of MIM feedstock has seldom been investigated …
