Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Back to the Mission. Revisiting Slack in Nonprofits and Introducing Tappable Slack

Nonprofit Management and Leadership, EarlyView.
ABSTRACT This article contributes to and develops the previous literature on excess resources (“slack”) in nonprofit organizations through a conceptual analysis of the implications that the organizational distinctiveness of nonprofits carries for our understanding of slack in these organizations.

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

Polymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

Evaluation of Mechanical, Thermal, Rheological, and Biocompatibility Properties of Additively Manufactured Metal‐Reinforced Biocomposites Optimized by Reinforcement Ratios and Printing Parameters

Polymer Composites, EarlyView.
Schematic illustration of PLA/316L stainless steel composite filament production via fused deposition modeling, demonstrating the trade‐off between stainless steel content, mechanical enhancement, and biocompatibility. ABSTRACT Polylactic acid (PLA) is a biodegradable thermoplastic widely used in biomedical devices; however, its inherent brittleness ...

Microstructure–Mechanical Response Relationship in Discontinuous Fiber‐Reinforced SMC Composites: Damage Mechanisms

Polymer Composites, EarlyView.
Architecture of SMC composites. ABSTRACT The mechanical performance of sheet molding compounds (SMCs) is dependent on microstructural characteristics determined by material composition and processing conditions. The study investigates standard SMCs, advanced SMCs (A‐SMCs), and low‐density SMCs (LD‐SMCs) under quasi‐static and fatigue loading to ...
