摘要：
Generation of electromagnetic signal pulses by brittle dielectrics loaded by nondestructive stresses is studied. For a given material, the emission intensity and the form of the electromagnetic pulse curves depend on the strength of sample as the load is increased. This dependence can be exploited as a nondestructive method for monitoring mechanical strength and detecting early damage in materials and manufactured products.
