ABAQUS/CAE

Iam working on the analysis of simply supported RC Slab using ABAQUS with Concrete Damaged Plasticity. Anyone knows the ideal or best data or expressions or formulaes to relate the yield stress and strain (or displacement or GFI) for tension behavior in the tension stiffening profile.

Please let me knows. Thank you.

I am trying to simulate creep damage in welded components in ABAQUS. I have four different sections in the same model assigned to four different materials. They are weld metal, base metal and Heat affected zones. I have to write a creep subroutine. For all the zones, creep equation is the same , but the parameters or constants change. i want to know how can I assign different parameters for different materials in the fortran source subroutine? what is the variable used for Material 1 , material 2 etc in standard ABAQUS?

Dear Abaqus Users,

I would like to model 3D composite structures using Hashin Damage model in ABAQUS. I have seen in ABAQUS manual that Hashin damage model is applicable only for shell element. I would like know whether I can use 3D element available in ABAQUS. Any help would be higly appreciated.

Dear All,

I am modeling rubber seal with hyperelastic material and I am using CAX4R Element for modeling. I achieved contact solution using initial analysis and as an output I got contact pressure and radial and axial displacement of the nodes.

hello everybody,

i'm very much new new to ABAQUS 6.7-4, which i'm using it in my project work.

i just wanted some help regarding the procedures or any kind of tutorial that will help me learnig the software.

thank you.

Hi all,
has someone experience with modelling soils in Abaqus? I am trying to model load test on board pile, some errors apear, like so many attempts made for this increment...too large fixed time, etc. I am pleased to share .inp file of analysis.

Hi,

Im really quite new to using abaqus and I am having trouble with my modelling.  Esentially it is quite an easy problem but my knowledge of the programme is limitted.  Basically all I want to model is an impact load on a wall but im not sure about the analysis steps.  Initially i have been using a static step with a concentrated load but I dont know how to model the dynamic response the wall should experience after the load has been applied.

If anyone can help with this I would appreciate it a lot.

Hi All,

 I'm really new on abaqus and currently having tremendous problem with it. Could anyone help with it? I'm trying to simulate a thin sheet clamped by rigid jaws and moves it onto designated position. Could anyone advice me on how to its boundary condition and so on.. ANy advice is welcomed. I'm really2 desperate.

Thanks in advance,

hi all

how the crack face unloading is done in Abaqus in 2-D model? i.e. how the nodal reaction force is brought down to zero while there is crack extension?

I'M USING ABAQUS IN MODELING A BEAM UNDER flexural, "BENDING".   my problem is the concrete material model with tension stiffening. my problem is occured repeatedly for all element types.
Although, i imported the input files obtained from the ABAQUS ducomentaion for support; the same error obtained.. the programe message is

The plasticity/creep/connector friction algorithm did not converge at 10 points

please help .. if  any one have a valid input file that represent the concrete model with the tension stiffening please send it .. thanks so much.

Hii All

i am using 20 noded brick elements with reduced integration to analyse stress and displcement fields in a simply supported beam. how can i control hourglassing effect? please give me suggestions. 

Hi,

 I am a new user here, and I have two problems to use ABAQUS/CAE,

the first problem, I need some tutorials or helps to simulate a coupled temperature-displacement in ABAQUS/CAE !!

 the second is the major problem, my project is in Laser Forming and I want use ABAQUS/CAE in this domain?

thank you in advance for your assistance
