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
please explain it(CoordMP)? It will be a great help for me.

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

C                                 slip planes

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.

Hi everyone,

 does anyone know publications dealing with the coupled thermo-structural analysis (direct method) of CFRP using ANSYS?

Hi

I have made a user element, UEL of a cohesive zone element. which is a 8 noded brick element with zero thickness. After solving models using this element I would like postprocess the model in abaqus CAE 6.10 in the way that I am able to:

hi,

I have to perform an non-linear buckling analysis over CFRP cylindrical shell in ansys. now i am little bit confuse how to perform this combined loading in ansys.in order to buckle some impurities (pertubation/imperfection ) must be included into the shell as this combine loading is purely in-plane loading case. this impurities i was including by performing a eigen value buckling during pure torsional loading and pure axial compression individually. but this is not much convinient during combine loading.

So my quries are

I'm currently working on my master thesis which is in the area of metal
forming simulation...

I have one question,,, when adding material plasticity in Abaqus using the
power law...

to what limit shall i go in the tabulated form is it to 100% plasticity or
to the maximum strain the material can take...

 in other word,,, if the power law is: σ =250*εp^0.123...

shall i inter the values till at σ=250, ε=1... or shall i stop at let say ε=0.25...

Regards,,,

Computational field of solid mechanics is mostly dominated by FEM.   This is a well known topic.

But is it that  FDM (finite difference method) has no chance of surviving
in solid mechanics?

What are the present developments in the use of FDM in case of elasticity analysis of solid body?

I would like to mention some of the recent research works on this topic here.....

Recently a new mathematical model has been developed by Prof. S. Reaz Ahmed and his students known as the "displacement potential approach".
