Dataset composed of two main parts 1. Material characterization of a metal (from lab test) Single file: metal-tensile.txt Material characteristics: - isotropic elastoplastic material with isotropic hardening - poisson ratio = 0.3 Geometrical characteristics: - specimen geometry: bar - initial length = 1000 mm - initial cross section = 35.28 mm^2 Loading characteristics: - uniaxial tension 2. Composite open-hole substructure characterization (from FE simulations) Multiple files: EaX_EbY_EsZ.txt (see README.txt for nomenclature) Layup: - [45/90/-45/0]s Damage criterion: - Hashin with cohesive damage propagation - No delaminations considered Loading characteristics: - Homogenized strain loading over the plate edges - In plane loading: different combinations of (eps_1, eps_2, eps_12) - In plane response: (sig_1, sig_2, sig_12), i.e. homogenized stresses
