A shear-lag model with a cohesive fibre–matrix interface for analysis of fibre pull-out
A shear-lag model with a cohesive fibre–matrix interface has been developed for the analysis of stress transfer between the fibre and the matrix in fibre-reinforced composites in this paper. A bilinear cohesive damage evolution law is used to describe the fibre–matrix interface behaviour. The governing equations for the interfacial shear stress and the axial stress in the fibre are derived. Acc...
متن کاملOn the Use of Planar Shear-Lag Methods for Stress-Transfer Analysis of Multilayered Composites
Shear-lag equations for analysis of stresses in a multilayered composite were derived using a series of approximations to exact two-dimensional elasticity methods. The shear-lag equations derived with the fewest assumptions was termed the Optimal, Shear-Lag Analysis for planar problems in composites. A solution method for these equations was outlined based on eigen-analysis of a matrix of shear...
متن کاملOn the Use of Shear-Lag Methods for Analysis of Stress Transfer in Unidirectional Composites
The “shear-lag” analysis method is frequently used for analysis of stress transfer between the fiber and the matrix in composites. The accuracy of shear-lag methods has not been critically assessed, in part because the assumptions have not been fully understood. This paper starts from the exact equations of elasticity for axisymmetric stress states in transversely isotropic materials and introd...
متن کاملA Revised Shear-Lag Analysis of an Energy Model for Fiber-Matrix Debonding
A shear-lag analysis based on energy is used to predict the amount of debonding that occurs when a fiber fragment breaks into two fragments. The shear-lag analysis reproduces all features of more sophisticated analyses. A drawback of the shear-lag analysis, however, is that it depends on an unknown parameter which can be expressed in terms of an effective fiber volume fraction. If the effective...
متن کاملGeneralized Shear-Lag Analysis Including Imperfect Interfaces
Two recent papers showed that shear-lag analysis can be an effective tool for stress analysis of composites when done properly and when applied to problems for which it is appropriate. This paper extends the prior analysis of concentric cylinders to a generalized shear-lag analysis in which the transverse variations of shear stress are described by arbitrary shape functions. The shear-lag analy...
