cantilever column

Submitted by hany_333 on

hello all,

i modeled a cantilever column with eccentric loading to simulate half of ordinary column, i get a small displacement at cantilever tip (equals 1/3 of reality,) so i want ahelp a bout updating geometry during analysis in order to getting effect of second order/nonlinear effects due to eccentric load.my software is ANSYS

thanks for all,

Constructing the extension velocity or updating the signed distance of a level set

Dear all,
I had been looking forward to use level sets to keep track of the surface in a simulation, but one thing has me stumped. Since many here work with XFEM, I was hoping someone might have some valuable input.

I want to simulate flows driven by a surface tension. This will typically yield holes, which will close rapidly. At the point at which the hole disappears, the signed distance function will have a discontinuity.
I would expect this to happen in pretty much any fluid simulation, but I can't see any way to handle it.

boundary condition in plate analysis

Submitted by M.Hassan Mansouri on

Dear All

 I have a problem with some theories in plate analysis such as bending and buckling of plates.

 you know that in various theories of plates, equations have different order and different number of boundary condiotions must be apply. for example in classisal theory of plates we have 4 B.C.,  and in first order shear deformation theory the number of B.C. are 5.

I am confused, how should I recognize the number of required B.C. in each theory?

 

Regards

Mansouri

A new ABAQUS user needs some guideline

Submitted by PrinceUS on

I am doing research in Bio mechanics field. I need to
get some urgent ABAQUS/Explicit result from my generated knee model
from MRI information. I am very very new user of ABAQUS. I need your kind
help.  In light of this connection, I am attaching one file regarding
to my quarries . if you kindly guide me for some few steps, I
will continue then on and it would be highly appreciable.

 I tried to post anot one input file. But I cannot do that hereby. If any one wants me to help me out , I will send that via your personal email.

i am new to Abaqus and i am unsing Abaqus 6.10

i planned to solve a contact problem by taking a bearing for example problem. i modelled the bearing section in pro-e and inmported it to Abaqus.

*i gave the material properties of steel for both ball and races

* in interferance i defined ball as master and the surfaces in the reces in the bearing as slave. frictionless.

* i gave pressure on the top race and arresteed the bottom race.

* the sides were given symentric with respect to y axis.

when solved i get the job is aborted.

Help in ABAQUS

Submitted by mahmood seraji on

Hi

I am using Abaqus to model the profiled steel sheet and the dry board will be attached to it. i have two question:

1) i have drawn the profiled sketch and have to extrude it to the proper length. if i do so, then how can i add some points in between the sheet in order to put some springs.

2) if i extrude the created sketch to the certain length (ex. 200mm), can i then copy the created model and paste it there to reach the desirable length for the sheet.

thank you.

help about secnd order effect in columns

Submitted by hany_333 on

ello all,

I am an M.S student, my subject in modelling of high strength concrete column under eecentric loading. I made a model of reinforced

 concrete column with in ANSYS by solid65 to represent concrete and link8 for steel.

My model is 200*200*4000 mm, i choose multi., conc.,and elastic linear for concrete, closing crushing for it, for steel bilinear, elastic.

Slenderness ratio (l/d)=20 Although Using large displacement analysis option, model give me very small displacement (less than
