Abstract
A modified Unsteady-Wave-Sensing-System (M-UWSS) is
proposed to standardize of the plate impact experiment combined with
in-material gauges in the target specimen for two kinds of materials, i.e.
polymeric and metallic materials. The M-UWSS has some unique features as
follows: (1) Nanosecond Lagrangian analyses are used to extract strain-time
histories from experimental stress data. (2) A new charge mode which measures
and computes the output charge of the PVDF gauge itself is used instead of
the usual charge mode which measures the charge of the output capacity.
(3) The phase velocity associated with stress passing through a metallic
target specimen is determined by considering the phase velocity of stress
across the in-material gauge, e.g., the manganin or PVDF gauge sandwiched
between the laminated target specimens.
