Hello!
While conducting a direct cyclic analysis, is it required to establish a static step before the cyclic step? If so, why should we use the static step and what conditions should be set up then?
Hello guys!
I had tried changing the mode of contact implementation. I was using a small sliding formulation with a node to surface discretization. I changed it to a finite sliding formulation and tested it for both node to surface and surface to surface discretization and it worked well...
Hello there!
I am conducting a simple simulation where I have placed 2 plates of equal dimension and thickness one upon another. I have pinned one corner and restricted motion in the z direction for the edge faces. I have applied an equal shear load on all the edge faces for both the top and...
Hello FEA Way,
Could you guide me as to how to do this modal analysis and what nodes to constrain rotations for? I should also mention that when I applied the same boundary conditions for a shell model without any bonding i.e, just a shell with 20 layers of composite, the model didn't rotate. I...
Hello FEA way,
I have attached a pic depicting the boundary conditions. I should mention that the total thickness of the model is 3mm, the top portion containing a single layer is 0.15mm thick while the bottom portion containing 19 layers is 2.85 mm...
Hello there!
I am attempting to conduct a delamination study of a square composite plate with a hole using the VCCT technique. I chose the VCCT because I intend on doing a low cycle fatigue analysis of the model later on. I had attempted this technique on a double cantilever beam problem with...
I did modify the input file too. I had to include the fatigue fracture criterion. I did get a warning but that was associated with the nlgeom being on in the previous step and not being on for the direct cyclic step. What stumps me is that when you run the sample input file, it directly jumps to...
Hello there!
I have been trying to model a crack propagation problem for quite some time now. I have taken a simple double cantilever beam as my problem of consideration. I am using a direct cyclic step and using VCCT debonding for modelling the crack. I have applied loads such that the double...
