Dear All,

I want to model a finite plate having a central semi-elliptical surface crack using ANSYS. I am still very new user, please help me to figure out how can I do that. I highly appreciate your help.

Thanks.

does ANSYS have a 3D crack tip element ? or a J-integral routine ?

have you read the manual ?

have you made a FE model before ?

there are some good references available (free) through NASA on this topic, search "JC Newman".
 
Yes I modeled a countersunk hole. Ansys has solid185 quarter point element which can be used to define the mesh at the crack tip.
 


How to model this crack and define the mesh around it
