✦ Synopsis

Almtract-T%is paper analyses the post-failure behavior of a three-point bend round beam specimen based on the idea of Carpinteri [J. Engng Me&. 115, 13754392 (1989)]. It is pointed out that the behavior of this specimen is different from that of Carpinteri's specimen with a rectangular cross-section in the snap-back instability. A new instability condition is proposed for the round beam specimen.

In this paper, the elastic deflection formula for a straight-through cracked three-point bend round beam is derived using an analytical method. If the crack tip plastic zone or fracture process zone is localized near the crack, its effect on the load line deflection can be considered through proper
