This tool will for the first time be able to address concurrently both microcracking induced stiffness degradation and cyclic loading induced delamination crack growth without remeshing. A physics-based deterministic solver will be developed by integrating a discrete crack network model with a multiaxial fatigue damage accumulation law. An advanced probabilistic analysis framework with the Bayesian Maximum Entropy (BME) updating procedure will be developed for risk informed total life management. The damage detection results will be integrated/fused with the physics based delamination growth prediction tool to form a risk informed damage prognosis and condition based maintenance metrics. Global Engineering and Materials, Inc. (GEM) has secured commitments for technical support from Clarkson University and Boeing, who will provide existing solution modules, supporting data, customization plug-ins, and expertise. The multi-faceted feasibility study consists of developing a method that will enable the prediction of multi-site, multi-mode damage interaction, extracting delamination driving force, characterizing delamination evolution under multiaxial non-proportional loading, and performing risk informed fatigue failure prediction and BME updating when new detection and maintenance data become available.","benefits":"Structural aging under fatigue loading is one of the most common failure mechanisms in civilian structures such as composite bridges, power lines, and composite ship structures. The developed probabilistic fatigue life prediction tool can be used effectively and efficiently to assist a designer and rule maker to answer the following questions: 1) How tolerant of cracks is the location? 2) How long to repair a crack in service? 3) What is the impact of an operational profile change? 4) How often should inspections be made? and 5) How can SHM input be used best? The tool can be used to assist commercial and military industries to reduce the cost of test-driven design and process iterations with the use of the virtual testing tool. Finally, teaming with Boeing, a highly visible airplane manufacturer, will considerably shorten our development cycle from producing a prototype research orientated tool to commercially accessible design software.<br /> <br />The results from this research will have significant benefits to enhance the aviation safety program in the NASA. It will result in: 1) a commercially viable, accurate, computationally efficient, and user-friendly probabilistic residual life assessment tool for charactering delamination crack growth and perform damage analysis with the presence of uncertainties in design and loading parameters; 2) an integrated analysis framework for fatigue damage prognosis and health management of composite aircraft structures; 3) a virtual testing tool to reduce current certification and qualification costs, which are heavily driven by experimental testing under various stress conditions; and 4) innovative probabilistic methods and reliability assessment procedures to facilitate the condition-based maintenance and reducing unscheduled maintenance.","releaseStatus":"Released","status":"Completed","viewCount":666,"destinationType":["Earth"],"trlBegin":3,"trlCurrent":6,"trlEnd":6,"lastUpdated":"01/22/26","favorited":false,"detailedFunding":false,"projectContacts":[{"contactId":2361772,"canUserEdit":false,"firstName":"Kai","lastName":"Goebel","fullName":"Kai F Goebel","fullNameInverted":"Goebel, Kai F","middleInitial":"F","email":"kai.goebel@nasa.gov","receiveEmail":"Unsubscribed","projectContactRole":"Project_Manager","projectContactId":537436,"projectId":8150,"programContactRolePretty":"","projectContactRolePretty":"Project Manager"},{"contactId":3164393,"canUserEdit":false,"firstName":"Jim","lastName":"Lua","fullName":"Jim Lua","fullNameInverted":"Lua, Jim","receiveEmail":"Unsubscribed","projectContactRole":"Principal_Investigator","projectContactId":537438,"projectId":8150,"programContactRolePretty":"","projectContactRolePretty":"Principal Investigator"},{"contactId":502006,"canUserEdit":false,"firstName":"Yuanjie","lastName":"Lua","fullName":"Yuanjie Lua","fullNameInverted":"Lua, Yuanjie","receiveEmail":"Unsubscribed","projectContactRole":"Principal_Investigator","projectContactId":537437,"projectId":8150,"programContactRolePretty":"","projectContactRolePretty":"Principal Investigator"}],"programContacts":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","email":"jason.l.kessler@nasa.gov","receiveEmail":"Subscribed_User","programContactRole":"Program_Director","programContactId":607,"programId":73,"programContactRolePretty":"Program Director","projectContactRolePretty":""},{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","email":"carlos.torrez@nasa.gov","receiveEmail":"Subscribed_User","programContactRole":"Program_Manager","programContactId":606,"programId":73,"programContactRolePretty":"Program Manager","projectContactRolePretty":""}],"leadOrganization":{"organizationId":3614,"organizationName":"Global Engineering and Materials, Inc","organizationType":"Industry","city":"East Lyme","stateTerritoryId":22,"stateTerritory":{"abbreviation":"CT","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Connecticut","stateTerritoryId":22,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"06333-1303","uei":"FDL9AWUAMKL1","cageCode":"4DVQ4","congressionalDistrict":"New Jersey 12","projectId":8150,"projectOrganizationId":565298,"organizationRole":"Lead_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Lead Organization","organizationTypePretty":"Industry"},"otherOrganizations":[{"organizationId":3614,"organizationName":"Global Engineering and Materials, Inc","organizationType":"Industry","city":"East Lyme","stateTerritoryId":22,"stateTerritory":{"abbreviation":"CT","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Connecticut","stateTerritoryId":22,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"06333-1303","uei":"FDL9AWUAMKL1","cageCode":"4DVQ4","congressionalDistrict":"New Jersey 12","projectId":8150,"projectOrganizationId":565298,"organizationRole":"Lead_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Lead Organization","organizationTypePretty":"Industry"},{"organizationId":4941,"organizationName":"Ames Research Center","acronym":"ARC","organizationType":"NASA_Center","city":"Moffett Field","stateTerritoryId":59,"stateTerritory":{"abbreviation":"CA","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"California","stateTerritoryId":59,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"94035","projectId":8150,"projectOrganizationId":565297,"organizationRole":"Supporting_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Supporting Organization","organizationTypePretty":"NASA Center"}],"primaryTx":{"taxonomyNodeId":11343,"taxonomyRootId":8817,"parentNodeId":11341,"code":"TX12.1.2","title":"Computational Materials","description":"Computational materials predict life, tailor or improve properties, and guide experimental validation.","exampleTechnologies":"Multiscale modeling, linking atomistic to continuum scale for life prediction modelling and tailoring of structural, thermal, functional materials;
