| Abstract Scope |
Laser driven shockwaves are being implemented in new materials processing technologies and applications across the globe. These applications are inclusive of additive manufacturing, impact welding, fatigue prevention and mechanical strength testing. Accurate models for laser driven shockwave characteristics in materials, primarily in the quantized values of peak pressure and duration, are critical for identifying processing parameters and predicting the corresponding material response. Recent studies have been conducted using photon Doppler velocimetry to measure these shockwave characteristics and the impact of common variable processing configurations. Results of these studies have demonstrated shockwave characteristics counter to several assumed models utilized in numerous other studies. New models and techniques for estimating laser driven shockwave magnitudes and duration are identified and contain important implications to enable shockwave applications to achieve desired outcomes. Examples of the shockwave data application in simulation through experimental validation are used to demonstrate the usefulness of the study findings. |
