Hello Everyone,<\/p>\n

 <\/p>\n

I am trying to model the stress- and strainfields in a layered system after fabrication, therefore I am recreating the fabrication process to see which internal stress acts after fabrication.
During fabrication a plain material is glued on the layered system, this step I did recreate by ekill and later ealive. However, after the ealive command and emergance of the glued material the geometry deforms which I don’t understand. It seems like the connections between the layers are suddenly gone (I defined beforehand all connections of each layer as connected). Layers seem to intersect and overlap between each other. Next to it, the internal stress changes completly, high stress suddenly appear in the region where the adhesive is modeled.<\/p>\n

In the image you see the first prinzipial stress before and after adding the material to the system with ealive at a temperature of 22°C.<\/p>\n

Does somebody know why my geometry is deforming and why the stress is suddenly changeing?<\/p>\n
