Hello All,

I'm new user in ABAQUS and I want to simulate and verify a critical crack-size in a pressurized pipe with axial and circumferential crack. Also, an important aspect, the crack is through-wall thickness. So, I'm faced with some doubts about its implementation in ABAQUS as following:

1 - Can I model the through-wall crack with shell ements based on line-spring (element LS3S)?
