On an Anisotropic Model for Progressive Damage

    Project Details

    Description

    Progressive damage is modelled from a continuum damage, i.e. a homogenization point of view, and physical measurable quantities are used as the describing parameters. Evolution of stiffness and evolution of strength are not directly coupled. For plane problems the stiffness evolution is modelled by the longitudinal moduli (in orthogonal directions), the shear modulus and Poissons ratio. The relative evolutions of these moduli are controlled by a principle of maximum energy dissipation.
