An Integrated Numerical and Bollard Pull Evaluation Approach for Early‐Stage Resistance and Thrust Assessment of a Small Craft

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Early‐stage hydrodynamic assessment of slender multihull vessels is challenged by limited geometric maturity, uncertain propulsion integration, and strong sensitivity to operating conditions. Under such constraints, reliance on a single analytical or numerical method may lead to misleading design decisions due to oversimplification or ...

Moisture Effects on the Dimensional Stability of Bistable Carbon/Epoxy Laminates

Polymer Composites, EarlyView.
Experimental and numerical approach for studying moisture effects on composite dimensional stability. ABSTRACT Bistable composite laminates are attractive because they can switch between two stable shapes without continuous energy input, enabling applications in morphing structures and energy harvesting devices.

Solids Conveying in Injection Molding Machines—Analytical Model for Smooth and Grooved Feed Sections Derived From DEM Simulations

Polymer Engineering &Science, EarlyView.
Understanding Solids Conveying in Injection Molding Machines – Dimensions. ABSTRACT Solids conveying is a key aspect for the design of polymer processing machines, especially for processes with high screw speeds, grooved feed sections, and material with low bulk density.

In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

Polymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

Memory-Dependent Derivative Versus Fractional Derivative (IV): Space-Dependent Derivative for Unsteady Heat Diffusion

Fractal and Fractional
In recent decades, the fractional derivative (FD) and memory-dependent derivative (MDD) have been borrowed for modifying the unsteady diffusion process. Yet, according to their definitions, only memory effects in temporal sense are reflected.
