Stress intensity factor on interface of two materials
-
-
Hi,
I am currently doing simulations on a 2D bimaterial sample (SS/aluminum; 1:2 mm) with in a interface edge crack of arbitrary length "a" and a bonded connection on the remaining interface edges. I use a thermal condition as my load and plane stress behaviour and weak springs as my boundary conditions.
Thanks for the support!
Unfortunately, I still don't understand how the program determines the distance "r" from the crack tip. See the following formula given in 1.1.2.3:
Any ideas? This also seems to be mesh related.
