Evaluation of Different Methods for Determining the Entrance Pressure Drop in Capillary Rheometry
Applied Rheology, 2008 Two approaches for determining the entrance pressure drop in capillary rheometry were compared with low-density polyethylene and polystyrene melts as test fluids. Direct measurements with the orifice die were found to yield higher values for the entrance

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones
Advanced Engineering Materials, EarlyView.A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Chemically tuned thin elastomer slab [PDF]
, 2008 We have considered a cholesteric elastomer slab whose thickness is smaller tan fifteen helix periods, immersed in a racemic solvent. We have calculated the reflectance and transmittance of obliquely incident circularly polarized light due to a ...

Volume changes measurement of elastomers using 3D DIC
Acta Polytechnica CTU Proceedings, 2023 The presented research aims at measuring the volume changes of elastomers using digital image correlation (DIC) in the 3D configuration (stereo DIC). The deformation measurement method in stereo configuration was applied during the mechanical testing of

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
