Improved modeling of the effects of thermal residual stresses on single fiber pull-out problem

The single fiber pull-out technique has been commonly used to characterize the mechanical behavior of fiber/matrix interface in fiber reinforced compo site materials. In this study, an improved analysis considering the effect of thermal residual stresses in both radial and axial directions is develop ed for the single fiber pull-out test. It is found to have the pronounced e ffects on the stress transfer properties across the interface and the inter facial debonding behavior.
