Ask for parameters in medelling crack propagation in concrete dam with ABAQUS

Hello every one.

I need your help. I am now learning ABAQUS, doing some practice with crack propagation. The example I am doing now is a gravity dam. I sincerely want to know some material parameters with concrete damage, for example, the Normal Mode Fracture Energy, Shear Mode Fracture Energy 1st direction and 2nd direction, etc. If anyone could provide them to me ,or recommand some books that share such parameters, I would be much appreaciated.

 

I am waiting for your help.

 

Thanks.

Run ABAQUS subroutines written in Fortran

Dear colleagues,

 I am a beginner in using ABAQUS subroutines, and currently come into the problem of running ABAQUS subroutines written in Fortran.

I have installed ABAQUS 6.11-1, Microsoft Visual Studio 2010, and Intel Visual Fortran Studio XE 2011 on my computer. However, when I run the test codes, there are the following errors:


Abaqus Laterally loaded piles

Hi all,

 I modelled a pile in sandy soil, the pile is subjected to a lateral load. I embedded the pile inside the soil. The soil if always over stiffened , can any one tell me why , why the soil is very very stiff, I used very small value for elasticity modulus. please help


Abaqus,How to define the direction of beam element by specifying an additional node?


When I analyze a quiet complex spatial structure, error information warn that: the direction of the beam element is
not correct.


From abaqus document 26.3.4 I know we can
nominate the direction of beam element by adding additional node.It is clear
that this node should be off the axis of the element,any additional constrians?

Continous orthotropic fiber direction in ansys

Dear Friends,

 I am going to simulate a wavy orthotropic fiber in an isotropic media with  ansys workbench. The fiber is solid and the material direction of fiber needs to be changed continously with the fiber direction. I attached the model. I will appreciate if any body can give me an idea?

 

 Kind Regards,

Abaqus Gui

Hi all,

I am making a little plugin for Abaqus but I am stuck. Can someone help me?

My plugin populates an AFXTable with some ID and Name, the user selects one of those rows and when he/she hits Ok, the Kernel script should receive the row that the user selected.

None of this is working!

I can populate the table, but when I select a row the kernel script receives an empty keyword! I can only fix that if I modify the text of a cell.

Even when I do that I get unexpected results.  This is the code:

from abaqusGui import *

from pysimplesoap.client import SoapClient

 

class CADECLaminateDB(AFXDataDialog):

 


Abaqus/Standard computational time

Dear colleagues,

 

is there any technique to reduce a computational time in Abaqus/Standard like it can be done in Abaqus/Explicit using an increase of the loading rates and performing mass scaling???

 

Thank you in advance!

 

Best regards,

abaqus problems

Good day to everyone....

Im new in the abaqus user... im here got some problem in my beginner stage:

 (i) what the units used in the abaqus? how can i ckeck it? 

(ii) what is means of the approximate size?

(iii) we can put the vertical load and horizontal load, but how i can put the load with the angle such as (10kN in 30o) 

(iv) how can i do if i want do the looping in my analysis, such as:

      after the intial boundary condtion stage, im obtain the stress and
strain result then i want continue my analysis until the final result
with equilibirum strain...    

      example:

Modeling non-linear material

Dear all

I would like to model two non-linear material as shown in the pictures in ABAQUS. But I can model it with its non-linearities. The model has been created with beam element. I used the classical elastic-plastic model using calibrations but because of elastic non-linearities the calculated plastic strain comes negative. please help me howI can model it

Abaqus- Nodal force and Reaction force

Hi,

What is the difference between the nodal force (NFORC) and Reaction force in abaqus. I applied some displacement in my model, when checking the Reaction and Nodal force at the same node, Nodal force is just half the reaction force. Then I did some experiment and applied some load on a node, after solution when i check the nodal force on the same node, it is half of the applied load. Why is it not  same as the load I applied? I am confused. Please help me.

 Thanks,

Anshul


Turning simulation in ABAQUS

Hi,

I have to perform thermomechanical analysis of turning process in ABAQUS as a part of my project.

Is there any documentation or tutorials available for it?

Kindly provide me with links if it is available.

Thanking in advance.


PFC 2D for discrete element modelling

Dear all,

I have just started using PFC 2D. I want to generate stress/strain curve for a compaction test (oedometer test). I have designed the walls and the balls as particles. I have problem assigning the velocity of upper y-wall that will be used for compression and obtaining the stress/strain relationship as a graph. 

Please help.

Thanks

About beam element in abaqus and ansys

I am interested in using beam element to do a nonlinear static analysis (may need to a dynamic analysis in the future), but have trouble to understand some of the key features of beam element in abaqus or ansys. My goal is to find a beam element (preferably general beam section) with a defined stress resultant yield surface (e.g., P-M-M yield surface). If possible, could also account warping degree of freedom.

UMAT subroutine

Hey guys,      

               I'm new to using subroutines. I have installed the Intel Fortram Complier v10.1 and using it for running the subroutine UMAT. I am first testing the umat subroutine for Isotropic elasticity as given in the abaqus manual for a single element with one integration point, but I'm facing the following error:

Unexpected error 193

Abaqus Error: The executable D:\SIMULIA\Abaqus\6.10-1\exec\standard.exe

FEA Software that simulate lubricated contact using Reynolds equation

Hello,

 

I am working in lubricated contacts and I want to know if it is possible to simulate that on ABAQUS software using Reynolds equation. If possible how can it be done ?

If it is not possible, there is another software that can simulate this kind on contacts ? 

Thanks for the help.
