How to manually apply Periodic Boundary Conditions in ABAQUS

This video is focussed on showing how to manually apply Periodic Boundary Conditions (PBC) in ABAQUS. This video shows a step-by-step process for using features within ABAQUS to convert a canonical equation into *Equation constraints within ABAQUS. This is done first by creating the virtual domain, materials, and mesh. The boundary nodes on the meshes are noted and converted into nodal sets individually. These boundary nodal sets are then subsequently used to create multifunction constraints equations which impose the periodic boundary conditions. The implementation has been demonstrated using a representative volume element (RVE) of a unidirectional composite. #pbc #abaqus #cmvideos
