Damage evolution in ABAQUS: Damage variable and displacement

Submitted by Gyanender Singh on

Hi,

I am using Abaqus to simulate crack propagation during 3 point bend test. In the Materials section I am defining the Damage evolution and I have chosen to specify softening in tabulated data format. Tabulated data will include damage variable vs. displacement. 

I am having difficulty in providing this data. If anyone has done some related work and know of some thing similar then please let me know.

Thanks,

Gyanender

Question about postprocessing in ABAQUS

Hello,

 I am using Abaqus for a structural analysis problem. In the results I have stress distribution over the structure. I can use odb file to see the distribution of stresses as a function of space and time. 

I want to plot stress at a particular node as a function of time (and may be also stress distibution w.r.t. space coordinates at some instant of time). I have some general idea about the result file that can be generated from Abaqus and can be accessed. I am reading more about it but I am not sure if this is the right way.

Hashin damage model for fiber reinforced composite in ABAQUS

Hi Everyone,

I am doing a project in which I am trying to study about the
drilling of composite. The aim is to optimize the drill and process
parameters to minimize the damage. For this I have tried to simulate
the drilling process in ABAQUS and I am using the Hashin damage model.
The problem is that Hashin damage model works only for the lamina which
takes only plane stress elements. Since only plane elements are allowed
I am unable to simulate cutting action of drill as the composite plate
is effectively 2D.
