In previous papers, the basic mechanisms of the ballistic effect, e.g. the fact that samples are ejected with high velocity, associated with the fracture of brittle materials during ultrasonic fatigue loading, were studied. In this technical note, the point of main effort is to extend the results su
Optimum experimental conditions for the brittle fracture technique applied in trace metal analysis of biological material are described. The efficiency of the technique was tested by siave and radio-tracer experiments. Numerical results are presented for human placenta submitted to eight different g
