LS-DYNA Tutorial 21: Concrete Column Wrapped with Composite Laminates

In this video, the concrete cylinder wrapped with composites laminates (glass fiber reinforced polymer) is subjected to low velocity compression. The concrete is modelled with MAT072REL3 and the composite laminates are defined with MAT054 using shell elements. This tutorial will be the first about composite modelling and the last tutorial for concrete. What I covered in this video: How to define concrete with MAT072REL3 including the damage parameters How to use EOS Tabulated Compaction for concrete model How to define the basic properties of composites with MAT054 How to use SECTION SHELL to define the number of composite layers and their orientation How to define PART COMPOSITE How to use Tied Nodes to Surface Offset How to change the angle of the shell and solid elements How to invoke the extra history variables How to make a rigid wall, stationary and moving How to extract the forces from rigid wall How to find the strain in the circumferential direction Referenced paper in this video: Gliszczynski (2018).
