The Influence of the End of the Incidence Pole on the KId of the Three Point Bending Specimen Tested by the SHPB

Abstract:

Article Preview

When the KId (dynamic fracture toughness) of the three point bending components is tested on the SHPB device, the signals of reflected waves obtained have been elongated because the end of the incidence pole is generally made by wedge shape. Through the conduction theory based on one dimension stress wave theory, the reflection and transmission phenomena of waves on the surface of the wedge have been analyzed. In the present paper, the loads acting the components have been modified, by removing the stress wave part among incidence and reflection waves reflected by the wedge surface.
