Abstract: Some artificial materials were constructed according to a types of different element strength distribution, and then the inner state of the material had been discussed in line to the relationship between change of image and exterior force. By element's lightness indicating the value of inner force, breakage and acoustic emission (AE), it suggested that the AE had close relationship to the chosen critical value. Different detect critical value led to different AE mode. Usually the energy emission would become stronger when the rock mass was going to break, so it was feasible to check AE and predict rock mass' breakage by larger critical value.

Key words: variational principle, acoustic emission, non-homogenization, image matrix
