Hi
I am modeling crushable foam.
i used uniaxial test data for propertise of foam from beginig of plastic. becouse i inpute young's modulus and poisson'ratio before in elastic.
in that properties in plastic/crushable foam there is necesery to input "compression yeild stress ratio" but it is not clear for me and i have a question:
Is it same with yeil stress point or no?
pleas descibe it for me if you know.
thanks
