Intensity of singular stress fields of an embedded fibre under pull-out force

open access: yesIntensity of singular stress fields of an embedded fibre under pull-out force
Previous experimental studies of fibre pull-out test show two dangerous points on the interface. Failure usually occurs at the bonded end of the fibre (Point A) or at the entry point on the surface of the matrix (Point E). Both points have different singular stress fields which causes crack initiation, crack propagation, and final failure.
