International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

On non-Newtonian fluids with convective effects
Electronic Journal of Differential Equations, 2017 We study a system of partial differential equations describing a steady thermoconvective flow of a non-Newtonian fluid. We assume that the stress tensor and the heat flux depend on temperature and satisfy the conditions of p,q-coercivity with $p>\frac{

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Rheological Characterization and Multi‐Regime Viscosity Modeling of Diluted Polyethylene Mixtures
Polymer Engineering &Science, EarlyView.This study maps the flow behavior of low‐density polyethylene in a recycling solvent from dilute solutions to entangled melts. By integrating time–concentration and time–temperature superposition, and coupling three complementary rheometry methods, a unified semiempirical model accurately predicts steady‐shear viscosity over nine decades of viscosity ...

Poly‐Ether‐Ether‐Ketone Melt Behavior in Fused Deposit Modeling Printing Moves
Polymer Engineering &Science, EarlyView.A thin solidified layer forms at the print bed during FDM of PEEK, reducing the effective shear height and raising the effective shear rate above the nominal value. Surface defects emerge once the effective shear rate exceeds a critical value of approximately 750 s−1.
