The response of strain gages to longitudinally sweeping strain pulses

Wave Propagation in Structures

“…is good to about 160 kHz. Other aspects of the use of strain gages in dynamic situations are covered in References [8,98]. Either constant-current, potentiometer or wheatstone bridge gage circuits can be used.…”

An Algorithm for the Input along a Davies’ Bar

“…The strain pulse does not change along the sensor [6]. The output signal represents the instantaneous average strain along the active grid [6, 7].…”

“…The static gauge factor is transferred to dynamic situations [4]. The propagation time of a pulse through the adhesive film and the strain gauge support is assumed to be equal to zero [5, 6]. The strain pulse does not change along the sensor [6].…”

“…The strain pulse does not change along the sensor [6]. The output signal represents the instantaneous average strain along the active grid [6,7].In a previous paper [8] the authors proposed a new methodology for the determination of the parameters defining the elastic wave along a Davies' bar. The methodology basically involves a much more detailed interpretation of the phenomenon than that provided hitherto.…”
