research

Dear Friends,

I have written a UEL for Strain Gradient Plasticity and is working well when i give Boundary condition as Concentrated force, But when i apply displacement boundary condition the it leads to 'system error 144'.

Iknow that system error 144 corresponds to division by zero or infinity, but then why it is coming in on displacement boundary condition is i am worried about.

I will be extremely helpful to anybody for any type of help on above problem.

Thanking you in advance

Hi i am try to model three-point-bend using abaqus, i have the tutorial file but dont have the three-point-bend.cae, do anyone have it, please help me

Dear Friends,

I have written an UEL for Strain Gradient Plasticity but it shows following error :

FE SOLVER AND MESH HAVE INCOSISTENT NUMBER OF DOFS

I will be very thankful if someone can throw some light on this error.

Thanking in advance.

Hi!



Good Day.



Please note that I want to model a pipeline
which is on ground surface using CEL. I have applied the geostatic stess
only in step-01. But at the end of step-01, pipe is starting to move
upward. I do not apply any force on pipe but it seems to me that pipe
experienced some force which push it to move upward. Also, I do not
apply any gravity load for pipe.





Please advice.



Thanks in advance.



Sincerely-

sujan
