Hello,

 

i try to simulate a adhesive connection between two solids.

 

First issue, i dont know how to create a adhesive connection, i tried to create it by Shell-elements (2D-->connectors-->area-->Type:adhesives), but i cant do it well. 

 

Second issue, how to create the adhesive connection by Solid-elements.

 

Thank you for your respond.

 

Muhammed

    in HM Help (always look at it) you will find the documentation of this panel 'area' and a tutorial showing how to use connectors area.

     

    If you're using OptiStruct there is also Cohesive Elements, since version 2019.2, i think.

    Thank u for your respond. I use optistruct 2017.2

     

    I try to superimpose my 2D Mesh with the 3D Mesh to create two identic Meshs at my solids to connect them with a adhesive. I will continue.

    the connectors adhesive needs some gap to create the solid elements, otherwise they will be squized.

    How can i create a adhesive Connection in a hole ? See picture. The Box of the prisma is a Solid. The Glasplate is also a solid.

    if you want to fill this large gap with adhsesive, then you should create a mesh for this hole and tie it to the rest of your model. I believe this would be the correct approahc.

    yes.

    depending on what you want, you could just create a TIE contact, bonding everything together. Otherwise, extract faces, close the open cap with shell mesh, and create the tetra mesh, with nodes connected.
