Hello,

I have a question to Abaqus users,

Can I simulate a drop-test of a model having crack in it in Abaqus/explicit.

If yes, whether Contour integral crack type can be used or I have to use XFEM?

Reply asap

how to define cohesive element property? because the cohesive element layer is our imaginary

Submitted by hanrrycn on

I'm modeling rock fracture problem with cohesive element. I konw the propertiey of the solid element around the fracture because we can measure it (rock sample) in the lab. but as regard to how to define the propeties of cohesive element, I'm completely lost.



in fact, the cohseive element is a fictitious one, not a real matearial in the physical world, we can't mearsure its propety by physical means. then how can we know what parameters we should enter ?



need your help, thanks

pictures and data of crack propagation experiment or example

Submitted by garyofcourse on
Hello,

I am looking for some data/pictures of crack propagation tests. More precisely, what I am looking for are test results of some 2D structure (or structures that can be modeled in 2D) where the experimenter has listed the geometry, material, loads and boundary conditions, and displayed photos of the crack that was observed propagating on loading the structure. Sort of like "heres a plate of dimensions a x b, made of material x, with an initial crack here, I now apply a load of magnitude M, and heres a picture of the crack that has propagated."

Post crack behaviour in ANSYS for concrete beam-column connection.

Have a prob in Analysing  FEM discrete model of Beam column connection [both monolithic and precast] for crack behaviour indisplacement controlled cyclic loading program.

 

Tried with various values of closed and open crack and co-efficient. 

applied -1 for crack and changed even the keypoint

in stiffness multiplier also 0.6 also set keypoint 7 to "1" instead of default value "0"

 

But even by all these the analysis runs only for 0.3mm of deflection..
