This paper proposes a dimensionless criterion—the acoustic-structure locking factor Λ_as—for quantitatively assessing the coupled resonance risk between combustion instability acoustic modes and structural vibration modes in liquid rocket engine combustion chambers.

This Research Note interprets the design features of the Starship V3 heat shield as an independent instantiation of the IFD core skeleton on an engineering interface. Quantitative Nvi estimates based on publicly available data yield Nvi ≈ 2.5 (Flight 10), ≈ 1.2 (Flight 11), and ≈ 0.6 (Flight 12)—a complete trajectory from interface yielding to the safe

This paper presents an acoustic emission-based early detection and warning method for lithium dendrite growth and interface degradation in solid-state batteries. The method exploits high-frequency AE signals from dendrite nucleation, collapse, and interface microcrack propagation to achieve early warning before electrochemical signal anomalies appear ...

Internal reference: SFM-2026-006. This paper extends the gradient-driven interfacial fatigue theory from wrought alloys to additively manufactured alloys, demonstrating the cross-manufacturing-route universality of the N_vi framework. It anchors patent defense on the manufacturing side by publicly disclosing the immunization post-processing protocol ...

This paper proposes a progressive damage model based on the Nvi criterion and modal locking coupling for assessing the residual life of combustion chambers after first spallation. The model consists of three modules: damage state diagnosis, modal reconfiguration prediction, and residual life estimation using a Miner-type cumulative damage law.

This paper presents a cross-scale unified theory describing non-equilibrium vacancy evolution from atomic-scale diffusion to macroscopic lamellar void coalescence. Based on the phase-field kinetic framework, coupled partial differential equations linking the vacancy concentration field, stress field, and damage field are established.
