3D crack modeling using CTMOPT macro in ANSYS

bhamarsd — Sat, 21 Jun 2008 16:52:44 -0400

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

i need a simple result of stress intenisty or J-Integral v.s length of crack front through thckness for check my resluts ( free surface to free surface). any body has please send my email adress (azim_120@yahoo.com) .

many thanks,

Dear All,

Can anyone give me more details on MPC184 element as used in ANSYS.

What is the importance of the contact type, and how does that value of force and displacement calculated in MPC184. I have read ANSYS help, but it is not clear to me.

Thank You

Dear All,

Here are two links related to 2D and 3D fracture analysis with ANSYS. These documents are in Turkish but full menu and ANSYS explanations avaliable there. I hope they will be useful for everyone.
