Effect Of Friction On Matrix Damage In Unidirectional Composites
An analytical model is developed for the study of fracture behavior of unidirectional composites containing a transverse crack and longitudinal damage. Of particular interest is the effect of friction on the growth of longitudinal matrix damage. A consistent shear lag constitutive relationship is employed to take into account the load carrying capacity of the matrix. The resulting governing equations are solved numerically. The initiation as well as stable growth of matrix damage can be predicted in terms of composite microstructural properties and damage configuration. The results show that the high stress region at the tip of a longitudinal matrix split influences the failure of the adjoining fibers. The introduction of friction within the matrix split in the form of a closed crack retards the split growth. © 1992 Taylor and Francis Group, LLC.
