Dear All,
I am modelling a 3 point bend specimen with Cohesive elements tied to the upper and lower halves of the specimen in 2d.
The problem is that the CZ elements perform properly only for a combination of element sizes, i.e. a combination of element size of structure and CZ elements, for...
Dear All,
In brief my problem is that in the axissymmetric model of a ball pressing a disk; I am getting load extracted as reaction force at RP of ball is higher than the experimental values.
The material property is correct; extrapolated to 1 strain
contact is also supposedly correct penalty...

Dear All,
I would like to have a simulation in which I can model both ductile and cleavage damage. For that I want GTN damage to run for some time and then I am planning to define a criteria based on f* of GTN to define cleavage. or if I want to implement GTN without using porous material...

I have a body of steel in which based on shear hydride will nucleate, so i have created orphan mesh and a code to assign hydride properties but this code should take the data from results in each increment as explicit algorithm.
I am modeling a body in which based on max shear stress the elements will change their material property. Please suggest how can I do it?
Can it be done without using subroutines( by python scripts) if not which subroutine, I should follow.
Any help will be appreciated.
Hello everyone :),
I am trying to write a code for FEA of solid structures (steels). Initially I am planning to get nodes coordinates and connectivities from ABAQUS input file and solve them/
For that I am considering 20 noded brick element with 6 dofs per node (three displ and three...
yes exactly,I too did not understand that whats the point in compressing but not deforming plastically....... but they r saying that they do not want much change in length and accrding to them, in machine the displc is say 12mm so they r comressing to 11mm so they sud not have problem, but i...
Thanks for your reply, i got some idea about what i needed from your reply, i guess.
provider of spring has done solid compression( not exactly but has compressed to 12mm ( to get a free length of 37mm apprx) well should not give these details here.
he compressed it thrice i guess, but what i...
well, i will first explain my task
I am working on very high cycle fatigue behavior of helical compression springs, right now I m involved in FEM modeling of it. I am not concerned with manufacturing. we have a special machine where we put around 576 springs of different rate/stress levels, and...
hey mike, thanks for your answer, but I have grounded surface at the top and bottom of the spring and there i can have pressure, but ja its actually a different machine in which 300 springs are being tested together and i have been going through many dramas with these springs.
as you said you...
