What about the duration of pulses in SHPB test in case of damage ?

11 February 2014 1 10K Report

For GRP composites, how is it the duration of the incident, reflected and transmitted pulses under compression SHPB test when the specimen is damaged?.

Larbi Gueraiche

The duration of pulses equals twice the length of the striker bar divided by the elastic wave speed (T=2L/c0).
