| Abstract: | The use of a recent analysis of fiber debonding and sliding in brittle matrix composites to interpret the results of fiber pulling and pushing experiments is examined. The stress-displacement relations are expressed in normalized forms that are convenient for curve fitting to experimental measurements and the analysis is extended to provide stress-displacement relations for cyclic loading in addition to monotonic loading. The ranges of some of the important elastic parameters and their influence on the stress-displacement relations are examined. Differences between single and multiple fiber pulling and between pushing and pulling experiments are assessed. |
