It is the same thing that I have done. I tried giving both mass and rotary inertia to my reference point and it does not work. However, as I mentioned before, it works when I choose moderate dissipation, but not in transient fidelity!
How should I specify mass apart from inertia? I created a Point mass/inertia using Special->Inertia->create and I could not find any mass apart from that.
I am trying to do a 2D dynamic implicit simulation and I have defined density for all parts in my model, except one part which is discrete rigid and I defined a reference point on it and I gave it an inertia. My model works when I use Moderate dissipation or Quasi-static options in step, while...
Than you so much.
I tried to apply these approaches for zero thickness cohesive elements. But I have the following problems with them:
approach a) As Abaqus does not allow to create parts from the sketch that intersect itself I created the whole domain as an object and using partitioning I...
Yes. You are right the problem is probably related to how I defined cohesive elements. But could you please let me know what should I exactly do? How can I edit coordinates of all nodes?
Another important thing is that I used a very thin layer of cohesive layer instead of zero thickness and my...
As far as I know, the options we have for the definition of damage in mechanical properties are
Damage for traction separation law
Damage for fiber-reinforced composites
damage for ductile metals
damage for elastomers
As I do not work on metals, composites, and elastomers, I think I should use...
I enabled element deletion in element type for cohesive elements but they do not disappear yet. Do you know what else should I check?
Yes, this analysis is similar to the approach has been used in a research paper. However, I am using my own geometry and material properties. Do you mean the...
I tried with displacement in Explicit as well. For both contact strategies (General and Surface-to-surface) I get similar results to previous ones.
I mean:
Defining displacement & General contact similar to Defining velocity & General contact
Defining displacement & Surface-to-surface contact...
Thank you for your response. I added mass/inertia to the rigid body's RP. But it did not change. The static and explicit models are totally the same. I just defined U2 for rigid body movement in the static simulation while V2 for explicit simulation.
I checked general contact for the explicit...
I am simulating the separation of two different parts which are connected with a thin layer of cohesive elements in a 2D explicit problem. The simulation is conducted successfully without error. But the final results shown in the visualization module seems very weird (see the attached...
I am simulating the separation of two surfaces connected with cohesive surface interaction in a 2D static problem in ABAQUS. Although using a coarse mesh everything seems ok, when I use a finer mesh to check mesh convergence I get this error: "Too many attempts made for this increment".
As I am...
