3D crack modeling using CTMOPT macro in ANSYS

Hello Everybody..

I am MS student in University of cincinnati, Oh, USA. I am working on
fractures in thin film and for  that i need to model 3D cracks. Problem
is i cant just use extrude comand becuase, crack is not throughout tht
length of the film ( So i cant use th eapproch mentioned above). there
is CTMOPT macro in ansys which allows to desgin meshing at the crack
tip. I am struggling with the ewxplanation given there. If anybody has
detail information in how to implelment this macro, please let me
know. 

Thanknig you,

Sagar Bhamare

sir

i m b.e. iv year student  and i do project on fracture behaviour of joints using ansys. and i have just basic knowledge of ansys so plz provide me sufficient information.

i will be very grateful to you.   

Hello, I am trying to run a laminted composite plate in ansys. I have all the required mechanical properties and the know how to put some of the information. So far, the many trials I did i can't extract the failure criteria results. I want to know whether the plate fails in normal, shear or compression. I appreciate if someone can give me the map of how to get to that result and at what force. what are the step that i have to take in order to get there.

thanks

IS IT POSSIBLE TO DO A  RC CIRCUIT   COUPLED FINITE ELEMEN ANALYSIS USING ANSYS

I want to couple RC circuit  with one end to conducttor and other end to work peice .and study the electric feild intensity in conductor nd work peice..

THANks in advance

I want to model moving mass on a simply supported beam in ANSYS but I can not reach to analytical results, I tried defining CPs and some other methods. I want to find a linear solution and I prefer do not enter in Nonlinear analysis.

Hi,

 I need to do the modelling in a command file instead of through the ANSYS graphinc interface as I need to try out different configurations and automatically run it in ANSYS. My question is:

 Say I create a rectangular geometry using the BLC4 command:

BLC4,-5,-15,80,100

I need to load the structure using the DL command? How do I know which side of the rectangel is assigned which line number? Can I control this? Is it consistent?

 Thanks,

Hi everybody,

 i?m simulating a manufacturing chain finite elements analysis. Every step of this chain have been developed by different software. I use ANSYS. Somoone know how to impose the initial strain and stress state deriving from previous simulations to my ansys model: I'm able to use INISTATE command but only stresses are imported, I loose initial strain info: are they important if my material is elasto plastic? how i can resolve the problem?

Thanks in Advance Michele

Hello everybody,

I am searching precision of crack propogation in a bonded wafer double.I wrote a code but the problem is that when I want to solve it in ANSYS, the program is shutdown. I need help about it. Thanks for your helps...

hi 

i am doing my PhD in  "smart composites"

i am working on piezoelectric composite materails... 
i will be greatful to you if anyone can suggest me  how to model the piezoelectric materials in ANSYS.i am having some doubts in meshing and giving the voltage input to ANSYS.

if i directly glue actuator to the beam using volume glue  then i am getting problem while meshing volume as "invalid topology for mapped brick mesh". how can i glue two volumes in ansys and avoid the problem in meshing???

expecting a response ....

Regards..
