COMPRESSION ROD HAVING A BUCKLING INITIATING FEATURE

摘要

A compression rod (10) has a buckling initiating feature (18). The compression rod includes an elongate body (12). The elongate body has a first cross sectional area along a first length (L1) of the elongate body and a second cross sectional area along a second length (L2) of the elongate body. The second cross sectional area defines the buckling initiating feature (18). The second cross sectional area is configured to cause buckling along the elongate body upon application of a predetermined axially oriented compressive force.
