Hi all
I'm working on strengthened a cracked steel plate with CFRP. I am using XFEM method for modeling the crack. When I use stationary crack ( no growing crack) and isotropic CFRP, I can request the KI ( stress intensity factor ) at crack tip but once I active crack growing option or once I use lamina with Hashin damage for CFRP I cannot request the KI at crack tip
When I activate the crack growing option I got this error” the history output requests are applied for XFEM crack which are not stationary XFEM crack”
When I use Hashin Damage I got this error “The elastic material along the crack front must be of the same type for the calculation of k factors”
Any idea or suggestion will be appreciated
Respected Hayder Al-Salih sir,
The field approached by you is very interesting and also vast, so more research can be done in this regard. It's very interesting topic. The following article link may help you for your kind information.

Thank you Dac Thuong Ngo for the nice explanation
Do you have answer for the second part of the question?
When I use Hashin Damage for the CFRP strengthening, I got this error:
“The elastic material along the crack front must be of the same type for the calculation of k factors”
even though the steel plate is isotropic and the crack is stationary.
I am also facing same problem for Aluminium cracked plate with Boron Epoxy Patch.
Can anyone suggest how properties of adhesive( Shear modulus and poisson ratio) can be entered in ABAQUS?
