hi...i m doing 2nd year mtech...i m getting an error while solving circumferential crack in cylinder using ANSYS...while calculating stress intensity factor(SIF) it shows the error as "all crack face nodes do not have the same z value in the currently active coordinate system"...please anyone let me know how to deal this error??
regards

I am doing a project in FRACTURE MECHANICS.I completed doing the TASK in 2D geometries now i am facing a problem of creation of CRACK in 3D.. The most important thing is i need to execute in ANSYS only through GUI not through CODING.....PLZZZZZ....HELP ME....... I am attaching the MODEL also ... The model is a PRESSURE VESSEL..... Plz... help ...me......
PLEASE FIND THE ATTACHEMENTS BELOW OF MY MODELS........
These notes were initially written when I taught fracture mechanics in spring 2010. The title of the notes was then "stress intensity factor". In revising the notes for the class in 2014, I have changed the title of the notes to "crack-tip field".
You can access all notes for the course on fracture mechanics.
These notes were prepared when I taught fracture mechanics in 2010, and were updated when I taught the course again in 2014.

I wrote these notes on the Griffith (1921) paper for a graduate course on fracture mechanics taught in 2010. The notes were updated when I taught the course in 2014, and were discussed in a new thread titled Inglis (1913) vs. Griffith (1921).
A body is subject to a load. What is the magnitude of the load that will cause the body to fracture? Let us begin with a body made of a glass, which deforms elastically by small strains. A procedure you have been taught before probably goes as follows. You first determine the maximum stress in the body. You then determine the strength of the material. The body is supposed to fracture when the maximum stress in the body reaches the strength of the material.
