Modeling the large - deformation and progressive fracture of propellants is arduous for grid - based techniques. To address Mode-I fracture behavior in solid propellants, this study develops a Non-Ordinary State-Based Peridynamic (NOSB-PD) model to simulate damage evolution and validates the results against experimental data. By correlating with the experimental load-displacement data, this study inversely identified the critical stretch in the peridynamic model.The fracture process exhibits three characteristic phases: linear response, progressive crack tip blunting, and ultimate propagation. NOSB-PD simulations successfully replicate both the macroscopic fracture patterns and mesoscopic damage progression, as quantified through damage field analysis. Compared with Bond-Based Peridynamic (BB-PD), the NOSB-PD model demonstrates superior agreement with experimental load-displacement curves and captures more nonlinear features of the fracture process. Moreover, the NOSB-PD framework provides direct access to full-field mechanical responses (stress/strain/displacement) throughout all damage stages, enabling time-space analysis of their complex distribution patterns.

Modeling the large - deformation and progressive fracture of propellants is arduous for grid - based techniques. To address Mode-I fracture behavior in solid propellants, this study develops a Non-Ordinary State-Based Peridynamic (NOSB-PD) model to simulate damage evolution and validates the results against experimental data. By correlating with the experimental load-displacement data, this study inversely identified the critical stretch in the peridynamic model.The fracture process exhibits three characteristic phases: linear response, progressive crack tip blunting, and ultimate propagation. NOSB-PD simulations successfully replicate both the macroscopic fracture patterns and mesoscopic damage progression, as quantified through damage field analysis. Compared with Bond-Based Peridynamic (BB-PD), the NOSB-PD model demonstrates superior agreement with experimental load-displacement curves and captures more nonlinear features of the fracture process. Moreover, the NOSB-PD framework provides direct access to full-field mechanical responses (stress/strain/displacement) throughout all damage stages, enabling time-space analysis of their complex distribution patterns.\u003c/p\u003e","manuscriptTitle":"Mode I Crack Propagation in Solid Propellants via Non-Ordinary State-Based Peridynamic","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-14 00:34:39","doi":"10.21203/rs.3.rs-7839572/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"editorInvitedReview","content":"","date":"2025-11-11T08:12:35+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"216511870914217273300642607042548428511","date":"2025-11-06T01:44:50+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"191104851399817401826399827965134838591","date":"2025-11-05T21:38:01+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-05T21:35:52+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-10-15T22:42:58+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-10-15T07:16:12+00:00","index":"","fulltext":""},{"type":"submitted","content":"International Journal of Fracture","date":"2025-10-12T09:01:48+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"international-journal-of-fracture","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"frac","sideBox":"Learn more about [International Journal of Fracture](http://link.springer.com/journal/10704)","snPcode":"10704","submissionUrl":"https://submission.nature.com/new-submission/10704/3","title":"International Journal of Fracture","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"ac86319b-209d-4df2-849e-76a8092c46f6","owner":[],"postedDate":"October 14th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2025-11-05T21:38:15+00:00","versionOfRecord":[],"versionCreatedAt":"2025-10-14 00:34:39","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7839572","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7839572","identity":"rs-7839572","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
