Code and data for: Process-zone condensation: a discretization-exact reduced cell model for FE² analysis of composites with fibre–matrix debonding and matrix plasticity

Code and data supporting the article "Process-zone condensation: a discretization-exact reduced cell model for FE² analysis of composites with fibre–matrix debonding and matrix plasticity" (L.T. Pedrini, M. Conci, R.M. Ferro), prepared for submission to Composite Structures.

The deposit contains the Python implementation of the full finite element cell, the process-zone condensation, the effective onset surfaces and the reduced FE² drivers, with its test suite; the saved results of every computation reported in the article (JSON summaries, CSV tables, reports and logs); the Ansys Mechanical APDL 2025 R1 macros, input decks and text exports of the independent reference analyses; the timing protocol and load logs; and the scripts that redraw every figure from the saved results, with SHA-256 manifests of their sources. README.md maps each table and figure of the article to the command and the result folder.
