Abstract:

Analytical work aimed at establishing velocity gage emplacement procedures for ground-shock measurement is reported. Finite element calculations were performed using nonlinear, inelastic material models, in support of experiments at WES using artificial soil specimens in the Small Blast Load Generator. The investigations covered a wide range of boreholefree-field impedances under a variety of interface conditions. Interface bond rather than impedance matching was identified as the principal requirement for fidelity of velocity measurement. Velocity gage canisters are, therefore, recommended to be locked to the free field with an expansive grout in the vicinity of the gage. Author
