FIBER PULL-OUT RESISTANCE BEHAVIOR SUBJECTED TO MONOTONIC AND CYCLIC LOADINGS

Abstract

 This paper presents test results of pull-out behavior of short fiber (PP fiber and steel fiber) subjected to monotonic and cyclic loading. In the case of PP fiber, pull-out resistance under cyclic loading was slightly decreased comparing to that of monotonic loading. In some cases, load was suddenly dropped due to split crack due to cyclic loading. In addition, bending of PP fiber induces a damage due to compression action in the test. In the case of steel fiber, frictional bonding behavior was observed in both tensile and compression phases.
