NL springs query
Hello guys,
I am working on a project wherein there is a rubber material which gets compressed. Now I have the force-displacement curve for this rubber material. I intend to represent the rubber with NL springs.
The F-d curve mentiones the specimen details as 5*100mm. This i beleive is the tested specimen. Now how can I consider this for the whole rubber model???
I have n number of springs connected in parallel. How can I consider this when I use a F-d curve?
Any help is appreciated.
Thanks.

Why not Gurson-Tvergaard-Needleman void growth model for plate impact simulations?
Can someone answer me if Gurson-Tvergaard-Needleman void growth model is not suitable for flyer-plate impact simulations? I have come across some papers who have derived void growth equations to simulate fracture in ductile mateials like OFHC copper etc., subject to plate impact (uniaxial strain high strian rate loading). I have attached 3 of them. But none of them have used Gurson's yield function. I did not find any explanation if GTN model has any drawbacks in simulating spallation phenomena found in plate impact simulations.
