On The Feng Failure Criterion For Composites
In this paper, the criterion is evaluated with experimental data for a boron/epoxy, symmetrically balanced, angle-ply laminate. The results prove that the failure states obtained by the criterion agree with the experimental data. Furthermore, the criterion also predicts whether the failure of a composite is due to matrix or fiber. The advantages for Feng failure criterion over other criteria are summarized, and the criterion is implemented into LS-DYNA for composite materials.
