Mechanics of Interfacial Failure during Thin-Slice Fiber Pushout Tests
Published online by Cambridge University Press: 15 February 2011
Abstract
Interfacial failure along the fiber-matrix interface during fiber push-out tests is examined for conditions where (1) a “thin-slice” specimen geometry is used and (2) matrix plasticity is necessary for large scale fiber displacement. The influence of both test geometry and the combination of thermally and mechanically induced stresses on the potential failure process is discussed. Experimental results are presented which illustrate a range of interfacial failure processes as a consequence of different combinations of specimen geometries, thermally induced residual stresses, and mechanically applied stresses. It is concluded that mode I crack opening and growth induced by specimen bending can be a major contributor to the interfacial failure process. Accurate quantitative measurements of interfacial shear properties must therefore rely on test configurations in which specimen bending is eliminated.
