Nonlinear responses of metals and composites

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
