New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design
This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

Numerical Simulation on Rock-breaking and Temperature Characteristics of Sawtooth PDC Cutter
Most of the researches on bionic teeth focus on the wave tooth shape, and there are few reports on the rock-breaking properties of sawtooth cutters.Based on plasto elasticity and Drucker-Prager rock failure criteria, a finite element model of interaction

The effect of wear of a cutting tool with a controlled depth of cut on the acoustic Emission
Проведено моделирование акустического излучения при износе обрабатывающего инструмента из композиционного материала. Показано, что при контролируемой глубине резания износ обрабатывающего инструмента приводит к возрастанию амплитудных параметров акустической эмиссии.
