The initial decomposition mechanism of FOX-7 (ε phase) at high temperature and pressure is simulated by ab initio molecular dynamics. We mainly studied the initial reaction of FOX-7 under extreme conditions of 10 GPa and 700-3000 K. When the pressure is constant, FOX-7 shows different decomposition mechanisms as the temperature increases. At lower temperatures, hydrogen is transferred first. As the temperature increases, the transfer of hydrogen and the breakage of the C-NO2 bond leading to the generation of acid are the main initial decomposition pathways. The energy barrier for hydrogen transfer is lower than that of C-NO2 bond breaking, which was confirmed by a single-molecule transition state search. Thus, the correctness of the decomposition mechanism obtained by molecular dynamics is proved. Different from previous studies, this paper considers both temperature and higher pressure, providing a reference for the initial reaction mechanism of FOX-7 under extreme conditions.KEYWORDS: Ab initio molecular dynamicsFOX-7initial decomposition mechanism AcknowledgmentsThis work was supported by the National Natural Science Foundation of China (Grant No. 12072299).Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author upon reasonable request and available within the article.Additional informationFundingThe work was supported by the National Natural Science Foundation of China [12072299].","PeriodicalId":15754,"journal":{"name":"Journal of Energetic Materials","volume":"8 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135042865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A robust tension-compression asymmetric phase-field fracture model for describing PBX cracking under complex stress states","authors":"Luoxia Cao, Hong Yang, Yang Zhou, Mingfeng Tang, Shengnan Wang, Huarong Li, Yong Han","doi":"10.1080/07370652.2023.2275199","DOIUrl":"https://doi.org/10.1080/07370652.2023.2275199","url":null,"abstract":"ABSTRACTThe crack behaviors under complex stress states are very important for the safety of polymer-bonded explosives (PBXs) under accidental stimulations, but their accurate description is a challenge. Due to the advances of tracking discontinuities and multi-fields coupling, the phase-field model for complex fracture phenomena is attracting significant interest recently. Conventional phase-field fracture models are tension-compression symmetric or based on volumetric-deviatoric strain energy split, and these conventional phase-field models may lead to unrealistic fracture patterns, which hinders its further application in PBX fracture simulations. In this work, we present an extended, tension-compression asymmetric phase-field fracture model for PBXs, which distinguishes the contributions of tensile and compressive stresses to damage driving energy, and couples the mechanism of mechanical degradation and energy-driving cracking diffusion. We implemented our improved phase-field fracture model into finite element calculations and compared the simulation results with the conventional tension-compression symmetric phase-field fracture model and volumetric-deviatoric strain energy split phase-field fracture model by simulating PBX specimens under static loadings. The results show that our model not only accurately depicts the tensile and compressive cracks, but also describes compression-assisted cracking while suppressing unrealistic damage nucleation caused by small amplitudes of local compressive stresses, making it a very efficient way of describing PBX cracking under complex stress states. This new model is both mathematically and physically concise, and convenient for numerical implementation. Moreover, the novel model can be naturally extended to simulate shock-induced dynamic and/or coupled fracture of PBXs because of its feasibilities for dynamic extension and multi-field coupling.KEYWORDS: Finite element methodphase-field fracturepolymer-bonded explosivesstrain energy decompositiontension-compression asymmetry AcknowledgmentsThe corresponding author acknowledges the financial support from National Natural Science Foundation of China (Grant No. 12202415).Disclosure statementNo potential conflict of interest was reported by the author(s).Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/07370652.2023.2275199Additional informationFundingThis work was supported by the National Natural Science Foundation of China [12202415].","PeriodicalId":15754,"journal":{"name":"Journal of Energetic Materials","volume":" 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135242406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we investigated the influence of the CL-20 solid content on the micro-size detonation performance. Preliminary research shows that when the content of the main explosive in the explosive ink is less than 92%, the detonation velocity increases with the increase of the content, and the detonation critical size decreases with the increase of the content. The micromorphology, molding density, explosive crystal form, mechanical sensitivity, thermal stability and detonation corner of the molded samples were tested and characterized. The results show that the internal particle distribution of the printed molded sample is uniform, without cracks and fractures, the crystal form remains ε-type, the mechanical sensitivity and thermal stability are reduced, and the detonation velocity after molding with 92% explosive ink reaches 7281m·s-1, which is critical The detonation size is 1×0.027mm, and the detonation angle can reach up to 160°, showing excellent micro-size detonation performance.
