Connector disassembling in simulation with deformable body 1

[Alex_80]

Hi,

I look for an expert in ABAQUS simulation. I am only studying mechanical systems. I test connector elements and if system does not meet deformable body it works good. But if it is meet reaction forces from deformable body the system is disassembling. May be I can not find correct word to add? Can somebody help me with it? I can send you inp file for simulation.

Problem desriprtion:

Result with distruction see on link

May be somebody knows some magic worlds, I missed

Thanks very much.

Which type of elements do you use for these block-shaped parts ? Are these individual solid elements (one element per part) ? Do you have contact defined in the model ?

Hi, Fea_way !
I use *Element, type=C3D8R, elset=El-J1
All cubes are individual. And of course I have the contact beetwin bodies. But not all. May be this is reason?

I can send my inp file with. One is withi MPC and one with connector elements. If it will be usefull.

I would try with more elements per block. You have to make sure that contact between them is properly detected.

Yes, please attach your inp or cae file here (you can upload it as attachment to your post).

Here two inputs.

It seems I have some ideas. Will check on Monday
