Hi everybody,
I have a question about the shear modulus of polymers. As we know, the general engineering polymers （rubbers） are highly extensible and elastic. The shear modulus，G， for the polymers subjected to the small-strain conditions, can be defined by G=NkT, where N is the number of network chains, k is Boltzmann's constant and T is temperature in Kelvins.

hello i am in my first contact with abaqus i worked with plaxis but i want to model a pile in cyclic load i think that abaqus is more complete than plaxis but can any body show me how to start using abaqus in geotechnical problem
best salutations
Hi my friends,
i am using Dracker Prager Plasticity model in abaqus 6.6, i am working on rock sample, this rock sample shows strain softening behavior not strain hardening, but you know that Drucker Prager can simulate both hardening and softening.
i have the stress-srain diagram from the laboratory test.
my shear criterion is linear, i choosed from Suboption Drucker Prager Hardening.
