摘要

The effects of fracture modes on the kinetic energy absorption were studied experimentally on thin-walled circular tubes under dynamic axial compression. Emphasis was put on stable progressive fracture of these shock-isolating structural elements, in order to obtain moderate load histories toward protection of the objects from serious impact damage. Some of the results of impact tests on tubes with surface grooves or with other edge configurations are summarized in this report.
