This is a long and heavy tutorial, so buckle up everyone!

Topics covered in this video, includes but not limited to:
How to make a simple sandwich structure
How to set up three point bending test simulation
How to model failure with ADD_EROSION
How to model styrofoam with MAT063 CRUSHABLE_FOAM
How to prevent negative volume error in solid elements
How to combat hourglassing in soft materials
How to 'glue' parts with tienodes contact
How to use apply velocity/displacement with BOUNDARY PRESCRIBED MOTION RIGID
How to extract the forces with BNDOUT option

As mentioned, I did the modelling of
EPS foam for my final year project. Here the link to the published paper:
