Microscale finite element modeling and bonding mechanism analysis of steel/aluminum during cold compression

This study establishes and validates a microscale finite element model to reveal that the mechanical interlocking in cold roll bonding of steel/aluminum evolves through three distinct stages—hardened layer cracking, fresh metal extrusion, and fragment rotation—where thinner hardened layers and higher compressive stresses enhance bonding by promoting denser cracking and deeper fragment embedding.

Thermo-Relational State Inference for Lithium-Ion Battery SOC Estimation under Dynamic Thermal Excitation

This paper proposes the Thermo-Relational State Inference Network (TRSI-Net), a novel deep learning framework that significantly improves lithium-ion battery state-of-charge estimation under dynamic thermal excitation by explicitly modeling how thermal evolution alters the historical relevance of terminal measurements through thermally conditioned recalibration and relational memory attention.

Hybridizing ES-MDA with RAGA and WSO: A Comparative Study for Characterizing Hydraulic Conductivity Fields

This study proposes and evaluates a hybrid optimization framework that integrates Ensemble Smoother with Multiple Data Assimilation (ES-MDA) to generate informed initial populations for Real-coded Accelerating Genetic Algorithm (RAGA) and War Strategy Optimization (WSO), demonstrating that this approach significantly enhances the accuracy, stability, and convergence speed of hydraulic conductivity field inversion compared to using the algorithms independently.
