In this short tutorial, I attempt to model the Double Cantilever Beam (DCB) delamination test. The two beams are made of Carbon Fiber Composite and two approaches were demonstrated for modelling the cohesive zone.

I apologize if this video is not up to my usual standard, I wasn't fully awake when I recorded this! 😂😂😂

In this short tutorial, I cover the following:
How to manually create cohesive elements
How to use MAT003 Orthotropic Elastic for modelling composites
How to use MAT138 Cohesive Mixed Mode material model
How to apply constant velocity on a node set with Prescribed Motion Node Set
How to attach two surfaces and introduce failure with Tiebreak Contact

Read more about delamination in my blog post here:
