Contact or Shared Topology
I am doing a static structural analysis of sandwich plate with pyramidal core and laminated facesheets. I want to setup my core(beam elements) to be bonded to the facesheets( shell elements).
I tried that by choosing firstly only a shared topology in the geometry design phase and afterwards only with two contacts, one bonded contact where master was the core and slave was the upper facesheet, and another one for the lower facesheet.
The two methods gave different results, although in the manual it is said that they should be the same..
I also tried to do both, shared topology and contacts, and again I had another different result in respect to the aforementioned two methods.
Furthermore I also have different results based on which design tool I use, Spaceclaim or Design Modeler..
I cannot evaluate which from all these results is the correct one, since all of them have a big difference from the analytical computation based on the theory/literature.
Can somebody please help me?
