Overhang Effect on the Contact State between the Three-Point Bending Specimen and Supports in Hopkinson Bar

Abstract:

Article Preview

The effect of specimen overhang on contact state between specimen and supports has been investigated by analyzing stress wave propagation in loading bar, specimen, and supports in Hopkinson bar. The results show that the time for loss of contact decreases with increasing overhang. The criterion is obtained for keeping the specimen contact with supports under a fixed of the specimen thickness and width.
