What is Applying PBC in Finite Element Analysis about?

Periodic boundary conditions (PBC) are used in finite element analysis to model an infinite material by applying constraints between opposite faces of a finite representative volume element (RVE). The document describes how to define PBC constraints in Abaqus using linear constraint equations between nodes on opposite faces, with the constraints enforced through a dummy node assigned a prescribed displacement value. An example is given to illustrate defining PBC for a 1x1 square RVE with constraints applied
