Why the VVF of GTN model within Abaqus keeps 0

GTN

I calculated an example of unaxial tension using GTN model offered by Abaqus. I followed all the instructions found in CAE User's and Analysis User's manual in Abaqus documentation. No error or warning was issued but the result seemed ridiculous, since VVF, VVFG and VVFN keeped 0 throughout the process while equivalent plastic strain keeped increasing(which showed the material had come into plastic deformation). I don't know what went wrong, looking forward to you reply.

Ice failure simulation

Submitted by santhosh_ajayy on

Hi,

  I want to simulate Ice failure simulation in abaqus. In my problem, ice is deposited between 2 components.

  While I am trying to move one compoents, the ice is restricting the movement of the components. Now I want to find out the force at which the ice starts to failure .

  any methods are available n abaqus., Plz let me know if any body knows abt this kind of simulation.

 

Thanks in advance

Abaqus: Composite delamination with cohesive elements

composite delamination
 
Hello,
I have to do a FEA regarding impact damage and delamination propagation in a CFRP specimen.
I have to do this using cohesive element in order to see the propagation of the delamination front in the material.
My problem is that I don't know how to do this in Abaqus.
I'll better explain: I can use this software but is the first time approching composite behavior and I really don't know how to model that.

Hello, 

I am new in using abaqus, please can any one help me with tutorials, book or anything that guide me on how to simulate failure and damage progressive in composite materials using abaqus.

Thanks you all

Abaqus Max Principal vs Max Principal (Abs) values

Submitted by Gayan Aravinda on

Hi every one,

                   Does Any one know the difference between Max. Principal values and Max.Principal(Abs) values in Abaqus ? I searched from there manual..but they have not mentioned in there manual too..could you please let me know the difference between those two parameters? Thank you very much.
