how we get the moment diagram from the stress if the ABAQUS is available for shell element

Dear all,



Pls be informed that I am using abaqus explicit to model my
pipeline that

embedded in soil. In standard, Coord 1 means x co-ordinate,
coord 2 means Y

co-ordinnate and coord 3 means Z -co-ordinate. But I can not
undestand the

meaning of CoordMP(nblock,j) in explicit. I want vertical
co-ordinates of some

elements of my model but if I put CoordMP(k,2) it shows
always a constant value

for all elements which make no sense.



Can you

Hi everyone,

      I just constructed a VUMAT which including 3 state dependent variables ( nstatev =3 ), let say these three state dependent variables each have a initial value of 10, 20 and 30, may I know how to assign these initial values into the simulation or VUMAT?

      So far I follow the manual to assign the initial value via input file with material properties command as below (the line started with "*Initial Conditions" is line 361):

Hi,

I am searching on multiscale simulation of polymer/metal ( mechanical propertices).

Cohesive zone model is used for this porpose.

Is there another models that can use for this issue and using MD data as input?

Best regards,

Hi all,

     I want to set up a critical shear strain - normal stress criterion, in UMAT by prof. Huang. For the strains it is easy to get a critical strain along a slip plane; but for the stresses the notation is quite weird. It is not the same! See below:

C       Array STATEV:

C       3*NSLPTL+1 - 6*NSLPTL  :  current components of normals to slip

Hi iMechanica,

I want to start a discussion on the current status of DEM modelling of granular media. I know that Luding has published many papers in this area. Please add to the current research on granular flow modelling like viscoplasticity, hypoplasticity etc and the  numerical DEM methods.
