Bungee Cord Modeling??
Bungee Cord Modeling??
(OP)
Cheers,
I want to model a bungee cord to apply force to a sledge like body. The problem with the bungee cords is a bungee cord cannot be compressed like a spring. It only exerts a pulling force when extended.
I would be very pleased if you can help me on how to model a bungee cord

or a flex model, using beam elements?

X=-1,0,1,2,3,4,5,6,7,8 etc
Y=0,0,0,0,0,0,1,2,3,4,5
does work
Another option would be to use a sensor to measure between the two ends, and only activate the sforce statement when that distance exceeds the required length of the bungee.
The string of beads method I proposed above does work but is pretty ridiculous, particularly while you are tuning it.
The beam element method looks do-able, but I've never done it.
