hello everyone..i am working on project of self healing study of Glass fiber reniforced polymer (GFRP) composite. i want to know how we can induce a micro crack in GFRP and is ther any technique except SEM to know the condition of crack.

Thank you

iMechanica is a fabulous resource;  just wanted to say a brief thank you to all who put this together.  Thank you!

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 

    I want to print complete assembeled mass, stiffness matrices  in ABAQUS. I was trying for this. I got some clue for this as follows:

*STEP
etc
etc.
*ELEMENT MATRIX OUTPUT, OUTPUT FILE=FILENAME.EXT, MASS=YES, STIFFNESS=YES, ELSET=ELSET_NAME

*END STEP

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, everyone:

A rectangular plate, simply supported at four edges, subjected to a partial load- a uniformly distributed pressure over a round area at the plate center. What is the analytical solution for the plate deflection?
