ansys

Dear All,

 I am using ANSYS 13.0 APDL to simulate a elastic model to calculate stress intensity factor. I got the solution successfully. However, I want to verify the answer with theoretical solution from crack analysis handbook. So I need to output the total force on a straightline. 

 I had tried to check the force on each node on the line. But the value is varying and different from each other. So I hope to figure out the total force on this line. Should I just sum up all the nodal force on this line? Or is there any other way to output the total force? 

iMechanica,

Using the ANSYS software, have any of you had any success with assigning distinct Hill's plasticity and Hill's creep constants to the same material?

Best Regards,

The software version I installed and used is 3.2 version. I created a
3-D brick and meshed it in ANSYS 14. Then, I output the .cdb file and
convert it using OSM 3.2 software. After that, I started FRANC3D 3.2
software and follow the guidance in the "Thin Shell
Tutorial v2.6". It was said that I have to check the surface coordinate
system by changing direction of "GREEN BARS to the Same X direction".  

hi every one

i am modeling a reinforced concrete beam in ansys, but should i only applying the load or should i make a load steps?
and if i must make a load steps......how to do it?

please if any one can put a text file for commands used to model a reinforced concrete beam and make a load steps ......that would be great

best regards

Can Anyone help me how to do creep modeling in ansys? 

I need to follow the creep law __>      effective creep strain (e at time t) = S. T. e^(-H)

S=(a0)^t.(sigma)^(a1) ;     T = t^(a2)+(a3).t^(a4)+(a5)t^(a6)   ; H = (a7)/[(theta)+273.16]

a0 to a7 are material constants.

I have the experimental data and tried to fit the curve in Ansys to obtain the material constants. 

I tried to follow the ansys help file steps. But facing erros messages.

If any one could give me a sample apdl code it would be helpful.

while carrying out a simple 2D analysis of welding of butt joint considering the source of constant heat flux and applying it at certain nodes as constant heat flux, i encountered a problem that it says that the temperature at particular node is exceeding the pre set limit and no solution is obtained. I am a freshman in Ansys so any help in this regard will be helpful

Hi guys,

I deal with modal analysis of  3D 'both clmaped' composite tube in ANSYS. I use solid elements and orthotropic model of material. Constants of this material are homogenized values of composite tube. So I meshed the tube and set the element coord system ESYS as cylindrical. The problem is with results, becasue after solving I get very low eigenfrequncies, i.e. first 100 eigenfrequencies are from 0 to 10 Hz  with step 1 Hz and it seems a bit weird.

Do you have any tips where the problem could be?

Thanks,

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.

Dear all,

Hi everybody,

I am trying to model a connection in ANSYS and analyse it under cyclic load (Earthquake Load). first of all I have done my 3D model in Auto CAD but I dont know how to transfer this to ANSYS!!!

Also I have the graph for the cyclic load which is based on number of Cycles (x-axis) and storey drift (y-axis) but I dont know how I am supposed to model this in ANSYS!!!! can anyone help me and guide me through this?! Thank you very much. 

Can anyone teach me how to make a butt welded joint using ANSYS? Or in other word, how to define two plate that had been bond together by welding. Thanks

i got three questions here.

1) If im using ANSYS, how am i gonna do a fatigue life prediction of a welded joint? The speciment is butt joint. I need to know the procedure.

2) If im using ANSYS nCode DesignLife, how am i gonna obtain the SN curve if im using FE Model or Multi-column?

3) If Im using ANSYS nCode DesignLife, what should i pick for the geometry if im doing on CTOD method of a butt joint welded speciment?

Thanks for the help. :)

Dear All,

Greetings to you. I am M. Faisal Riyad from Bangladesh. I am going to assist one of my professor in his research. The research will about crack propagation analysis. He asked me to learn about the cohesive zone modelling approach in ANSYS. I am searching for some good articles to learn from the beginning. I would be very grateful to you if anyone help me to find the articles or any other way to learn about cohesize zone approach in ANSYS.

Thanks,

Faisal 

can anybody tell me how to model composite plate in ansys??  And how to solve it? Specify me what type of element should be used.

Dear All,

I have much problem when modelling my project with ANSYS, one of problem that I met always like this 

 *** ERROR ***                           CP =     296.828   TIME= 14:56:15
 A small negative equation solver pivot term has been encountered at the
 ROTZ degree of freedom of node 11758.  Check for an insufficiently     
 constrained model.

Dear friends,

Looking for a possible solution of a problem with external axial friction moment on a shear bolt.I tried to get literatures related with this type of combined loading,but not succeed much.If u can help me it would be great!

Hi

I needed a help regarding ansys macro. I need to process a text file and use the data of the text file for further post processing. Is it possible to exceute an exe file from ansys macro and to read external text file using ansys macro commands
