Abstract
It is shown that the acoustic emission obtained from plates and tube specimens for which failure is dominated by fibre fracture can be described analytically. The approach which is taken proposes a means with which the importance of failure mechanisms other than fibre fracture can be quantified. Overloading is seen to be equivalent to an acceleration of time at the lower load. The limitations of this analysis are explored and it is shown that certain structures are not amenable to this approach.
