Abstract
A method and apparatus for inspecting a rupture initiation in an article. While a load is applied to the article repetitively, an elastic wave is monitored by an elastic wave sensor which converts it into an electric signal. The electric signal is fed to a signal transmission device having a capacity of transmitting low-frequency components of the electric signal. The transmitted electric signal is divided into successive signal segments. The successive signal segments are averaged to produce an averaged signal waveform informing the presence of a rupture initiation in the article.
