FEA analysis on webbing strap

[leo88188]

Hello everyone!!!

Could anyone help me how to conduct an FEA fabric analysis..The Application is lifting a cargo bags using using polypropylene polyester strap..I know how to conduct simple FEA analysis in solid part....But this one needs to consider the weft and strands of the straps..Is there a method or plug-ins for this type of analysis???

Anyone, pls. help..

Unless you own a supercomputer I suspect you will end up modelling the strap as a a specific solid material, with certain unusual material properties.

Thanks Greg...It is greatly appreciated-----cheers..

Interesting problem. In more capable FEA systems, the webbing could be modelled with membrane elements. Not sure how to pull this off in COSMOS.

Perhaps you want to send the strap out for testing and then mimic it with shell elements with appropriate material properties.

I don't see how the problem is any different from using ropes for lifting, other than the propertiea would need to be found. It's just a hand calc to determine the tensile forces of the slings at some angle, surely?

" this one needs to consider the weft and strands of the straps."

That's the weird bit.
