A Methodology for assembling overset Generalized Grids
, 2004 The first step in the assembly of an overset grid system is to cut holes or to mark points that are inside a solid body and outside the domain of interest. Most existing approaches have been developed for use only with structured grids. A fast and robust

Transferable Hot‐Deformation Flow‐Curve Modeling Across Steels Through Transfer Learning
Materials Genome Engineering Advances, EarlyView.We propose a transferable sequence model that moves steel hot‐deformation ML beyond the “one‐case, one‐model” paradigm. Pretrained across compositions/windows and personalized with four extreme‐condition curves, it improves accuracy and robustness in 10‐fold evaluation.

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains
Naval Research Logistics (NRL), EarlyView.ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Optimal Designs and Inspection Time Decisions for Gamma Accelerated Degradation Tests
Naval Research Logistics (NRL), EarlyView.ABSTRACT This study analytically derives optimal designs for gamma accelerated degradation tests while incorporating inspection time as a design variable under both D‐ and V‐optimality criteria. Under D‐optimality, we prove that the optimal design allocates test units exclusively to the lowest and highest stress levels and adopts the longest inspection

Polymer Composites, EarlyView.The graphical abstract presents the experimental and data‐driven framework used to investigate the dry sliding tribological behavior of CFRP and GFRP composites. The effects of seawater, engine oil, diesel fuel, aging time, and normal load on the specific wear rate (SWR) and coefficient of friction (COF) were evaluated using pin‐on‐disc tests, ANOVA ...

Advances in parallel overset domain asembly [PDF]
, 2016 The CFD (Computational Fluid Dynamics) community has long used the Overset Grid method to enable dynamic simulations with bodies in relative motion. In Overset simulations, information is transferred between overlapping grids via interpolation.

Polymer 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‐
