โœฆ Synopsis

The stress-intensity factor and the size of the crack opening have been calculated for a linearly viscoelastic strip with a slowly propagating central crack. The edges of the infinitely long strip are displaced normal to the crack and both clamped and shear-free strip edges have been investigated. The results are based on the solutaon to the problem of a suddenly loaded strip with a stationary crack The resulting integral equation has been solved numerically for arbitrary crack length and analytical soluttons in form of asymptotic series are given for crack length up to about haft the strip width. The response to a propagating crack IS found by superposition * This work represents part of a Ph.D.

Using a new single complex function, this paper gives a general solution for a semi-infinite moving crack in a strip, supposing that the surfaces of the crack are subjected to an arbitrary self-equilibrium distributed anti-plane shear stress and other boundaries are clamped. This solution can reduce
