Subj: Modelling rubber in SAP2000
 
hi all,

I am right now doing a work on modelling a rubber material in sap2000.

i wanted to know if there was any built in material property for rubber in sap2000 or whether it had to be a user defined material.

Also, if it is user defined what are the properties that i would have to include to model the same.

i found the following details but would like to know more.

Natural Rubber
density = 930 kg/m^3
ultimate strength = 16 Mpa and Poissons ratio= 0.5

Also is there a value of the modulus of elasticity ?
