Laser interferometer techniques were used to research elastic precursor (EP) velocities in natural uranium samples 3–10 mm in thickness. A complicated elastic precursor shape was recorded, which might be explained by the shift and turn of constituent elements of the deformed continuum. The elastic precursor release jitter and velocity dispersion were measured to a spatial resolution of ∼0.1 mm (with respect to different interferometric lines there are recorded different elastic precursor amplitudes and profiles). Microstructure studies of samples after loading showed that average distance between shear bands at elastic precursor are in good agreement with the interferometry measurements. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR] |
