BAM SDCHABOX Calibration Workflow — Jupyter Notebook with IWM Knowledge Graph Integration.
This notebook implements the full material parameter identification and knowledge-graph publication pipeline for the SDCHABOX creep model applied to IN718 superalloy.
Workflow sections: 1. Environment setup (conda pyiron_env, JupyterLab 4.5.8, anywidget 0.11.0) 2. Setup Project (BAM) — simulation input generation, experimental data pre-processing 3. Optimization Process (BAM) — three-stage parameter identification: Differential Evolution (global) → Nelder-Mead (local) → Single-step refinement 4. Validation (BAM) — independent validation against held-out experimental data, produces IN718_SDCHABOX_validation_report.txt and comparison plots 5. KG Generation with CKAN Uploads — zips experimental data, uploads material card (.mat.best), validation report, generates Excel KG template with CKAN URLs populated, converts to Turtle (TTL) RDF, and uploads to dataportal.material-digital.de 6. Material Card Extraction via SPARQL — queries the Fuseki triple store to retrieve calibrated SDCHABOX parameters as a pivot table (CSV) 7. Material Card Pass (MCP) — generates a self-contained HTML Material Card Passport from 6 SPARQL queries covering provenance, software/infrastructure, input parameters, calibrated parameters, linked files, and material information; publishes to CKAN
Key technologies: - PyIron Workflow (pyiron-workflow ≥ 0.17.0) with PyironFlow GUI - BWMD ontology (Fraunhofer IWM) for knowledge graph schema - Apache Jena Fuseki SPARQL endpoint (hosted on dataportal.material-digital.de) - CKAN data portal (dataportal.material-digital.de / organization: digitalmodelling) - SDCHABOX constitutive creep model for IN718 superalloy (BAM)
Dynamic naming: all output filenames are generated from MATERIAL_ID and MODEL_NAME (configurable in Main.txt), enabling reuse for new materials and models without hardcoded path changes.
