How to model a layer of thermo setting polymer in abaqus?

Submitted by sandra tsen on

Dear all, I am modeling a 3 plies plywood using abaqus. I am facing some problem in modeling the resin layer which bond the wood veneer. Does anyone know how to model a layer of thermo setting polymer in between 2 ply of long grain direction wood veneer? Many thanks!   

How to understand the shear modulus of polymers

Submitted by Lianhua Ma on

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.

question about "Extended Dracker Prager plasticity model"

Submitted by Gamal on

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.
