Modelling of viscoplastic properties of epoxy resins in fibre-reinforced unidirectional composites - Data & Codes

This dataset contains the complete supplementary material associated with the publication:
Feyen, V., Breite, C., Chevalier, J., et al. (2026). Modelling of viscoplastic properties of epoxy resins in fibre-reinforced unidirectional composites. Mechanics of Time-Dependent Materials, 30, 12. https://doi.org/10.1007/s11043-026-09855-7
The dataset provides experimental data, numerical simulation results, and computational tools used to develop, calibrate, and validate the viscoplastic constitutive model for epoxy resins presented in the article.
The dataset includes:
- Experimental data from constant strain rate (CSR) tests and hold-at-load (HAL) tests performed on RTM6 and 736LT epoxy resins.
- Simulation output files corresponding to the numerical analyses discussed in the paper.
- Post-processing scripts to reproduce all graphs and figures presented in the publication using the provided simulation data.
- Fortran subroutine files implementing the viscoplastic epoxy creep constitutive model for use in Abaqus.
- MATLAB script (SubroutineCoefficient.m) used to identify and calibrate the constitutive model coefficients.
- Abaqus model files, including: .cae files for compression and tension simulations and .inp input files required to reproduce the experimental setups and numerical results reported in the article.
