Numerical analysis of the effect of ice-metal interface stress singularity on bonding failure

Abstract

ABSTRACTThe formation of ice on the surface of the metallic casing of high-end equipment poses a potential threat to its operational safety and stability. One important factor that contributes to bonding failure at the ice-metal interface is stress concentration. This paper aims to investigate the effect of stress concentration on the bonding failure behavior at the ice-metal interface through numerical analysis. First, the forms of bonding failure are categorized. Afterwards, the stress distribution state at the corners of the ice-metal interface is determined by the interfacial stress singularity. Finally, numerical analysis is carried out to investigate the thermal stress distribution law at the corners of the interface during the cooling process of the ice-metal bonding, so as to elucidate the induced mechanism of the interfacial stress state on the bonding failure. This study can provide some reference and guidelines for the study of bonding failure at the ice-metal interface.KEYWORDS: Ice-metal interfacebonding failurenumerical analysisstress concentration AcknowledgmentsThe authors gratefully acknowledge the financial support from the National Natural Science Foundation of China(No. U20B2033).Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe authors attest that all data for this study are included in the paper.Correction StatementThis article has been republished with minor changes.
