Hi everyone,
I am working on the propagation of an edge crack in semi-infinite plate under antiplane loading.
I need to estimate the stress intensity factor KIII at the front of the crack but I can't find a theoretical formula for this purpose. For an embedded crack of length l in an infinite plate under shear stress sigma_23 I can use KIII = sigma23*sqrt(pi*l). But I don't know what I must use in the case of an edge crack.
I was wondering if anyone knows of an analytic Solution for KI and/or KII in tubes.
I´ve seen an infinite number of equations, shape functions, FEM simulations, standards, etc. But one closed solution for tubes?, an analog to Williams series but for cilindirical surfaces?
how to do a crack propagation analysis?
can abaqus be used for doing crack propagation analysis for plates with multiple cracks?
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)?
