An Approach for Computationally Efficient Yet Accurate Modeling of Vibrating Machines With Neidhart Springs

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Accurate modeling of vibrating machines equipped with Neidhart springs is challenging due to the strong nonlinearities introduced by the elastomer–metal torsional elements and the constraints imposed by their kinematic arrangement. Multibody modeling methodologies for such vibrating machines are often computationally demanding, thus limiting ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

Additive Manufacturing of Glass Fiber‐Reinforced Polypropylene and Its Behavior Under Controlled Hydrogen Exposure

Polymer Composites, EarlyView.
Experimental and numerical assessment of GFRPP under lower experimental hydrogen pressures using tensile testing, SEM analysis, and hydrogen uptake estimation. ABSTRACT Glass fiber‐reinforced polypropylene (GFRPP) composites are increasingly explored for hydrogen transport and storage due to their lightweight nature and corrosion resistance.

Development of Sustainable Cellulose Acetate‐Based Filaments for 3D Printing Through Plasticization and Natural Wax Incorporation

Polymer Engineering &Science, EarlyView.
Schematic illustration of the forest‐derived filament production for 3D‐printing. ABSTRACT The integration of renewable biopolymers into value‐added engineering applications has become more critical. Cellulose acetate (CA) is a naturally derived polymer and widely used in the design‐oriented optical industry.
