Simulation of the Rotational Molding Process of Polyethylene Using the Smoothed Particle Hydrodynamics Method

open access: yesPolymer Engineering &Science, EarlyView.
Numerical simulation of polyethylene rotational molding using the Smoothed Particle Hydrodynamics (SPH) method. ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐

Validation of Electrostrictive Performance of P(VDF‐TrFE‐CFE) for kHz Range Applications

open access: yesJournal of Polymer Science, EarlyView.
This study demonstrates that the high‐frequency deformation of the relaxor ferroelectric polymer P(VDF–TrFE–CFE) is governed by Maxwell's electrostriction, confirming its suitability for fast electromechanical applications. Combining original high‐frequency mechanical characterization, laser vibrometry measurements, and numerical modeling, a ...

Weibull Variational Autoencoder for Remaining Useful Life Prediction

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Remaining useful life (RUL) prediction is a critical technology for preventing unexpected failures and reducing maintenance costs in modern industrial systems. However, traditional model‐based approaches are limited by the need for explicit mathematical modeling of degradation mechanisms, while data‐driven methods often require large‐scale ...
