Progressive Matrix

In this paper, a five-layer model is proposed to analyze the anisotropic constraint effects on interactive damage progression. Incorporating this model with the general theory of overall moduli of a cracked body, the effective damage factors proposed by Fan and Zhang in 1993 have been extended as quantitative measures for characterizing the anisotropic constraint effects on damage-induced stiffness reduction of general lay-up composites. By applying the first-order shear deformation plate theory to each sublayer these factors are determined and applied for investigating progressive matrix cracking-delamination interaction. Results show that by this rather unique approach, the intractable problem of anisotropic constraint effects of general lay-up composites on interactive damage progression can be handled in a systematic manner.

Good Agreement

The reduction of stiffness properties due to transverse ply cracking in [μθ m/90 n] s laminates loaded in quasi-tension is examined theoretically. Predictions of a simple theoretical model based on a modified 2-D shear-lag analysis, are in good agreement with experimental data. The energy released as a result of matrix cracking is also calculated and used to predict crack initiation and multiplication.

Progressive Matrix

Matrix cracking-induced delamination in composite laminates is qualitatively and quantitatively investigated in a finite element framework. The phantom node method is extended to incorporate breakable interfaces at transverse matrix crack tips. New user-defined element types in Abaqus improve the numerical stability in a geometrically nonlinear analysis. The new formulation allows for accurate prediction of matrix crack density and stiffness reduction in a number of composite laminates. Furthermore, the advanced phantom node method is able to simulate progressive matrix cracking-induced delamination with good accuracy.
