Wire Rope Failure
Wire Rope Failure
(OP)
I am a crane and rigging engineer seeking information on a subject to which there seems to be little knowledge. I am searching for data relating to wire rope failure due to a sudden release of load. Particularly, I'm looking for any data that suggests a threshold of EIPS 6x36 IWRC or EIPS 6x19 IWRC Wire Rope, to which damage such as "birdcaging" or "popped-core" is produced from certain sudden release of tension and resulting rebound of the wire rope from its loaded position.
If you have any recommendations or if you could point me in the right direction, I would greatly appreciate it.

A metallurgist is really the one that actually raised the standing wave scenario. I was amazed at the stress results...

The offshore drilling industry has a policy of recording ton -miles on the wire rope used on the Hoisting drawworks, and cutting and slipping the line at certain intervals.
Wire rope failure and birdnesting are common occurences when these running service guidelines are not followed

The book was from Lincoln Welding, something like "Practice of Weldaments" or so. It is an excellent source which served me well.
Still available online orders from Lincoln, by the way! Recommended bedtime reading for those interested. Good luck with your research.
