Current state-of-the-art is simulation of only partial parts. Separate models are used at different scales (microstructure, melt-pool, larger thermal) without integration. We will scale & automate layer-by-layer whole part simulation, add advanced physics of evaporation, and overlay microstructural metal phase modeling.","description":"We will combine part-level FEM model of residual stresses with phase-field transformation model to predict deformation and cracking due to thermal stresses from the AM building process. Next steps include fully-coupled, part-level thermo-mechanical simulation of the additive manufacturing process for assessing feasibility of employing an additive part on mission, and development of journal article and infusion into Glassgen's computational materials program, NESC and OSMA NDWG, STMD Rapid Analysis and Manufacturing Propulsion Technology (RAMPT), AMSII.","destinations":[{"lkuCodeId":1546,"code":"INSIDE_SOLAR_SYSTEM","description":"Others Inside the Solar System","lkuCodeTypeId":526,"lkuCodeType":{"codeType":"DESTINATION_TYPE","description":"Destination Type"}}],"startYear":2017,"startMonth":10,"endYear":2018,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":274756,"canUserEdit":false,"firstName":"Kevin","lastName":"Wheeler","fullName":"Kevin R Wheeler","fullNameInverted":"Wheeler, Kevin R","middleInitial":"R","primaryEmail":"kevin.wheeler@nasa.gov","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":335305,"canUserEdit":false,"firstName":"Michael","lastName":"Lapointe","fullName":"Michael R Lapointe","fullNameInverted":"Lapointe, Michael R","middleInitial":"R","primaryEmail":"michael.r.lapointe@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":392233,"canUserEdit":false,"firstName":"Richard","lastName":"Howard","fullName":"Richard W Howard","fullNameInverted":"Howard, Richard W","middleInitial":"W","primaryEmail":"richard.w.howard@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":176367,"canUserEdit":false,"firstName":"Harry","lastName":"Partridge","fullName":"Harry Partridge","fullNameInverted":"Partridge, Harry","primaryEmail":"harry.partridge@nasa.gov","publicEmail":true,"nacontact":false}],"website":"https://www.nasa.gov/directorates/spacetech/innovation_fund/index.html#.VQb6gUjJzyE","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"ARC CIF","active":true,"description":"Through the Center Innovation Fund, the Space Technology Mission Directorate allocates a small portion of the NASA workforce and procurement budget to internal research and development to feed early stage innovation in technology and exploration.
