How to model lattice structures with periodic boundary conditions.

This video shows how to model lattice composite structures using periodic boundary conditions (PBCs). The simulation is done with ABAQUS and periodic boundary condition is implemented by a software developed by CM Videos called #PBCGen2D. We have done this simulation using a 2D representation of a body-centred cubic structure with two aluminium face sheets. The video shows the principle behind the modelling, the setup of the virtual domain and setup of the model in ABAQUS, implementation of PBCs using #PBCGen2D and finally analysis of the simulation results as contour plots and qualitative data. #cmvideos #abaqustutorial #latticecomposites #rve #pbcgen2d #periodicboundarycondition Time stamps -------------------------------------- You can quickly navigate through the videos using these chapters. 00:00 Intro 01:28 Theory: What are lattice composites? 01:45 Theory: Modelling approach 02:07 Theory: virtual domain and materials 02:57 Theory: Periodic Boundary Conditions (PBCs) 03:58 PBCGen2D: software for imposing PBCs 04:19 Case studies considered 04:43 ABAQUS: Setting up of the lattice composite model 12:13 ABAQUS: Setting up model for PBCs 14:47 PBCGen2D: Apply PBCs to lattice cell model 16:40 Running ABAQUS simulations in MATLAB 17:15 Visualization of contour plots simulation results 18:43 Visualization force-displacement simulation results 19:36 Outro RELATED VIDEOS ----------------------------------- 1️⃣Lattice structure and unit cell: An ABAQUS modelling #abaqus - https://www.youtube.com/watch?v=h6KpCx4KAU4 2️⃣How to PLOT Stress Strain curve in #ABAQUS for a PBC-enabled RVE - https://www.youtube.com/watch?v=qHt-Mn3nuiQ -------------------------------------- ?* DOWNLOAD LINK TO SOFTWARE 1️⃣ PBCGenLite: A software for applying periodic boundary condition (limited version) - https://cmvideos.ck.page/products/pbc-gen-lite-v1pt0 2️⃣ MontCarlGen2D: A software for creating random inclusions in 2D RVEs Download software here: https://cmvideos.ck.page/products/montcarlgen2dv1 3️⃣ PBCGen2D: A software for applying periodic boundary condition (full version) Download software: https://cmvideos.ck.page/products/pbcgen2dv1 ----------------------------------- ?♂️ TIP JAR: If you want to support the channel, you can leave a tip here.
