Dear all,
I need to give properties of geosynthetic material in ABAQUS. Right now, I am giving as linear elastic material. Is it the correct way to give as linear elastic?, If it is appropriate to give as linear elastic, what way of deriving the properties is realistic. I have wide width tensile test results with me. Suggestions would be really helpful.
Regards

The tensile ranges of popular geosynthetic materials are very high. So under service loads, it is okay to assume a linear elastic behaviour. You can counter check the analysis results with your tensile tests. If the stresses in the material anywhere are crossing the tensile strength, nonlinearity is to be considered.
Hi Prashanthi
Linear elastic model is fine. Be careful about choosing the elastic modulus. The strain range should not exceed the elastic limit from your tension test. Poisson's ratio can be generally taken in the range of 0.3-0.4.
