abstract

  • Hou and Hashin criteria were compared under dynamic conditions, analysing the failure of beams subjected to low-velocity impacts in a three point configuration. To accomplish this goal a progressive failure
    model was implemented in a finite element code to predict the failure
    modes (fibre tensile failure, fibre compressive failure, matrix
    cracking, matrix crushing, and delamination), considering both Hou and
    Hashin criteria. The experimental results, from tests conducted in a
    drop-weight tower and available in the literature, were used to validate
    the numerical model. This model, using both criteria, was used to
    analyse the failure modes of two lay-ups (unidirectional and cross-ply)
    tested in two experimental devices (drop-weight tower and split
    Hopkinson pressure bar). The main failure mechanisms in both laminate
    lay-ups were also identified.
