3D Crack analyses using ANSYS

Submitted by Dan Sathiaraj on Wed, 2007-08-29 13:40.

i m dan doing ME Engineering Design.I m doing project in the area of probabilistic fracture mechanics.,So i need how to find SIF,J integral,Energy release rate,CDOT  for all type of crack (2D,3D)..,I want some of the material related to this..,i m using Ansys..,so complete step by step procedure in Crack analysis using analysis i want 3d Crack analysis

3D Fracture Analysis with ANSYS

Submitted by Mesut UYANER on Wed, 2008-03-12 15:00.

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.

MPC 184

Submitted by Nishant Shah on Mon, 2008-04-14 04:54.

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

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,

3D crack modeling using CTMOPT macro in ANSYS

Submitted by bhamarsd on Sat, 2008-06-21 20:52.

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
