Radioss explicit - Adhesive failure

mvass

Hello,

 

it has been a number of years since my last question on the ability of optistruct/radioss to tackle problems of glue failure/delamination of composite structures. Then I saw this presentation from 2016:

and the picture from page 22:

 

Does anyone know if the model depicted is available? This is exactly what I was looking for.

 

Thank you for your assistance.

Yes, LAW59 is able to model adhesive. /FAIL/CONNECT sometimes is used along with the material card to describe failure behavior.

 

 RD-E: 4802 Solid and Spring Spotweld in Crash Box in the example guide explains some details. It uses LAW59 to model spot weld, but modeling adhesive is similar concept. I attached the files for the example guide for your reference.
