“…The TEM analysis of laser-shocked pure copper has been described in detail elsewhere [3][4]. The discussion is briefly presented here solely to demonstrate the effect of Qualitatively, these results confirm previous observations, albeit at a pulse duration that is lower by a factor of 10-100 than that applied by Murr [20].…”

“…Today, laser shock and isentropic compression experiments are rapidly evolving as effective methods to explore the extreme pressure, strain-rate and temperature regimes inaccessible through other techniques [3][4][5]. Although laser shock compression does not yet have the temporal and spatial uniformity of pressure as plate impact experiments, it has a significant advantage, especially from the point-of-view of recovery.…”

It is shown that the short pulse durations (0.1-10 ns) in laser shock compression ensure a rapid decay of the pulse and quenching of the shocked sample in times that are orders of magnitude lower than in conventional explosively driven plate impact experiments. Thus, laser compression, by virtue of a much more rapid cooling, enables the retention of a deformation structure closer to the one existing during shock. The smaller pulse length also decreases the propensity for localization.

“…If the tensile stress is sufficiently high, voids can nucleate around particles or defects in the material and grow. Spall and the resulting damage have been studied extensively for shock loading created by gas guns [1][2][3][4] , explosives [5][6][7][8] and laser ablation [9][10][11] .…”

“…[1][2][3][4][5][6] Through the interaction of a pulsed high-intensity laser beam and an energy absorption layer on the metallic target surface, a shock wave with a high amplitude can be generated and propagates into the target. 2,[7][8][9][10][11][12][13] If the amplitude of the shock wave exceeds the Hugoniot elastic limit (HEL) of the target material, plastic deformation occurs and residual compressive stresses are induced near the surface, which results in the enhancement of fatigue life.…”

The shock pressure generated by the glass confined regime in laser shock peening and its attenuation in the target material are investigated. First, the particle velocity of the target back free surface induced by laser generated shock pressure of this regime is measured using a photonic Doppler velocimetry system. The temporal profile of the particle velocity at the back free surface, where the elastic precursor is captured, manifests a powerful diagnostic capability of this newly developed photonic Doppler velocimetry system for tracking the velocity on short time scales in shock-wave experiments. Second, a coupling pressure analytical model, in which the material constitutive models of confined layers and target material are considered, is proposed to predict the plasma pressure profile at the surface of target. Furthermore, using the predicted shock pressure profile as the input condition, the dynamic response of the target under the shock pressure is simulated by LS-DYNA. The simulated back free surface velocity profile agrees well with that measured by the photonic Doppler velocimetry system. Finally, the attenuation behavior of stress waves and particle velocities in the depth of the target is analyzed, and it indicates an exponential decay. The corresponding empirical formulas for the attenuation behavior are given based on the numerical results.
