Viscoelastic Abaqus Analysis question please help

Submitted by hdayanan on
Forums
Computational Mechanics Forum

Hi Everyone,

I am new to thermal viscosity analysis, here is the data I have received.

 

DMA data which has Temp, Shear Storage Modules, Shear Loss Modules,  Tan Delta, Calculated Modules, Temp was raised at 5 deg/Min

I want to do a thermal analysis where the part is heated upto 90 deg for 1 hr, returned to room temp and cooled 2 hours.

 How can i simulate this in abaqus ..? I want to incorporate the Viscosity data from the DMA data. I also have received  thermal conductivity, thermal expansion and specific heat data.

Dear friends,

I want to share our recent research work on NiAl nanowire, which is published in Nanotechnology, IOP publishing. The abstract of the paper is given below. Further details can be found at "Vijay Kumar Sutrakar et al 2009 Nanotechnology 20 295705 (9pp)   doi: 10.1088/0957-4484/20/29/295705"

 

Large deformation and electrochemistry of polyelectrolyte gels

polyelectrolyte

Immersed in an ionic solution, a network of polyelectrolyte polymers imbibes the solution and swells, resulting in a polyelectrolyte gel. The swelling is reversible, and is regulated by ionic concentrations, mechanical forces, and electric potentials. This paper develops a field theory to couple large deformation and electrochemistry. A specific material model is described, including the effects of stretching the network, mixing the polymers with the solvent and ions, and polarizing the gel.

Characterising fracture toughness in epoxy using mechanical fatigue. Help!

Fracture Mechanics Forum

Hi all,

I have taken up this research project/attachment on
"characterising the fracture toughness of epoxy using mechanical
fatigue", and encountered lot's of problems while researching. I'm just
a student, not even in university, but rather still schooling (grade
10), so am completely new to this field, which explains my problem in
understanding all the lit reviews, lecture slides i found online.
Luckily, i found out this site, and would hope that someone can guide
me in the right direction!
