Element nodal force in FEM

Submitted by sbbehravesh on

Hello every one,

I'm wondering if any body knows how does ABAQUS (or ANSYS) calculate "element nodal force" (not unique nodal force)? According to ABAQUS manual I just know that it is obtained from element stress. I couldn't find the procedure of calculation in ABAQUS help and manuals.

Thank you so much,

Behzad

Dear professors

 Could you please help me to get an MATLAB code for non linear analysis of simply supported beams please.

Hi,

I am working on a coupled fluid structure problem , precisley on the elasto-acoustic mode, of a system consist on a cube which define the fluid domain coupled with an elastic plate.

The boundry conditions is:

- all the face of the cube is regid only the face coupled with the plate

- the plate is simply supported at the interface

Hi everyone:

   I am henry, a graduate student in USA. These days, I am trying to make a zero thickness cohesive zone with curvature. After I define this and get everyting set up, then submit the job, the warning windows pop out and tell me the following error messages:

The node numbering might not be correct for element 2010 instance cohesive-1

The node numbering might not be correct for element 2010 instance cohesive-1

The node numbering might not be correct for element 2029 instance cohesive-1

Ansys (Composite) Postprocessing

Submitted by Hallgeirda on

 

Hi

Need to get results from an relatively big composite model, after running a nonlinear analysis.

Can anyone tell me how to get out max tsaiwu at top and bottom of (17)layer(s), for the different substeps(50) in a table form. This can be done manualy, but is a "nightmare" and takes a lot of time..

Am familiar with the Monitor command, that will give me the displacements through the different steps.
