Anti-plane pull-out of a rigid line inclusion from an elastic medium

doi:10.1007/s10483-023-2980-6

Abstract

Abstract: The transient and static anti-plane problem of a rigid line inclusion pulled out from an elastic medium is studied. The singular integral equation method is used to solve the stress field. Under the static load, the stress intensity factor (SIF) at the inclusion tips increases with the medium length. The problem becomes equivalent to an inclusion in a medium with an infinite length when the length of the medium is 3.5 times longer than that of the inclusion. However, under the transient load, the maximum value of the SIF occurs when the medium length is about two times the inclusion length. Besides, the relation between the pull-out force and the anti-plane displacement is given. The conclusions are useful in guiding the design of fiber reinforced composite materials.

Key words: pull-out, rigid line inclusion, anti-plane, stress intensity factor (SIF), stress singularity
