Hi everyone

 
I need a NASA article and I have few information about how to get access to it. Here is its title and hyperlink.

Dear All, 

Recently I have read some literatures on Molecular simulation of polymer. My interest is measurement of

mechanical properties of polymer through the uniaxial tensile test.    

I have a question about relatively large time scales in MD simulations of polymer and how to interpret MD

stress-strain results for FE modeling. In particular, in the literature it is mentioned that strain rate of

Dear All,

 I have seen it being mentioned that the material at an updated configuration in an Updated Lagrangian Formulation (say in FEM) may not remain isotropic, even if the reference configuration was isotropic.  However, I have not seen any detailed discussion on the matter.

Hence, I would request your comments on:

Hi all ,

       I am simulating Cohesive zone simulation of polymer coated steel using abaqus 6.9 ( Room Temp ).  The thickness of steel plate is 0.8mm ( 800 Micrometre). Thickness of PET ( Poly Polyethylene terephthalate ) is 0.03 mm ( 30 micrometre ). Cohesive zone is defined in between these two materials with zero thickness. I use standard traction seperation method embedded in abaqus 6.9. I have the following questions

(a) Regarding material properties,
