Modeling Graphene Adhesion and Dry Transfer using Cohesive Zone Models and Classical Beam Theory

摘要

We have studied competing interface fracture using FEM simulations and analytical models for applications in graphene transfer. Results show that interface strength is the major factor affecting the success of transfer and fracture energy of the damaged interface determines the loading conditions needed for steady state crack growth. Analytical model results are in agreement with the simulation results and scaling analysis gives us the exact dependence of load and fracture growth on material and interface properties.
