LS-DYNA TUTORIAL 10: Three Point Bending of Sandwich Structure with EPS Foam as Core

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: https://www.hindawi.com/journals/mse/... (do check it out and hope you can cite if it is helping you in your own research!) 😁😁😁 Here is the link to the stress-strain file: https://drive.google.com/open?id=1_1p...
