New Features and Improvements

This Pull Request includes a massive development of CRATE and yields the first version deemed ready for its open-source release. Besides many new code features and improvements, the new version includes a proper src/ layout, all the required Python package distribution files, a complete Sphinx documentation (with automatically generated API) and a directory of benchmarks. The coding style has also been improved, closely following the PEP8 guidelines, and a Flake8 configuration file has been included for the sake of coding style uniformity and automatic checking.

Below is a brief list of the main developments introduced in this version:

  • Massive OOP refactorization.

  • Extension of CRATE to finite strains.

  • Enrichment of available matricial and tensorial operations and procedures.

  • Improvement of FFT basic scheme implementation.

  • Enrichment of homogenized strain-stress output file.

  • Implementation of St.Venant-Kirchhoff anisotropic hyperelastic constitutive model.

  • Implementation of general isotropic elasticity.

  • Initial guess of RVE effective elastic tangent modulus available from the offline-stage.

  • ASCA equilibrium problem converted to total formulation (total strains as primary unknowns).

  • ASCA equilibrium formulation without the far-field strain was removed.

  • Add input data file option to keep the reference material properties constant.

  • The spatial discretization file directory can now be specified as a calling argument.

  • Removed some clustering algorithms implementations (not validated).

  • Removed some optimizers implementations (not validated).

  • Add new output file with the CRVE effective tangent modulus.

  • Add new input data file option to minimize the output to the essential.

  • Generalized Swift strain hardening law to Nadai-Ludwik.
