Hi,
I am trying to solve a 3PB specimen with a notch. I am doing the dynamic explicit analysis. I want to find the J-integral. Giving the J-integral as history output. Trying to run it gives following error.

Stress intensity factors for a slanted crack under compression
Hello everyone,
Here is the problem I have: I'm modeling the geometry of a simple straight edge crack in a 2D elastic medium using Abaqus. I assume plain stress conditions. The crack makes an angle with the horizontal, is small enough to be considered as embedded in an infinite domain (ratio crack length/size of domain < 1/10) and I apply a vertical compressive load on top of my domain. I fixed one point in displacement at the bottom of it and the whole bottom edge is constrained not to move vertically.
Strain energy release rate of beam specimen using J-integral

Hi All,
Are there any good references showing the detailed derivations of elastic strain energy release rate using J-integral instead of differentiating compliance for end notch beam samples : DCB, 3/4 point bend ...? many thanks ...
