In case when both plastic deformation and brittle fracture take place in approximately equal proportions, the mixture of two types AE results either in [U.sup.*.sub.RMS] increase or in continues AE superimposed with high energy burst signals.
On the strain rate dependence of acoustic emission during hydrogen-assisted cracking of high carbon steel
We have learned how to produce clean steels, we can assure ourselves that a weldment is sound, and we can determine whether the structure is susceptible to an unanticipated brittle fracture. None of the procedures used to accomplish those goals were viable tools in 1944.

The energy required for brittle fracture is proportional to the square of a characteristic dimension, which can be depth of cut, the energy required for plastic deformation is proportional to the cube of the characteristic dimension: the energy ratio of plastic flow to fracture is therefore proportional to the characteristic dimension.
