摘要：

A model for jumps in subcritical growth of plane cracks (of arbitrary shape) is proposed for three-dimensional bodies and the accompanying acoustic emission (AE). An approximation method for determining the displacement field resulting from one jump of the crack, based on the fact that the required solution is found in the comparison of displacement fields obtained from currently known problems in crack theory, is proposed. A series of new analytical relationships between parameters of plane cracks in three-dimensional bodies and parameters of AE is given.
