Imperial College London Graphene Composite Simulation Case Study
Researchers used Abaqus FEA to simulate graphene and carbon-fiber microstructures, improving fracture toughness and damage tolerance modeling for aerospace composites.
Imperial College London aeronautics researchers developed molecular-dynamics methods inside Abaqus to link macro-scale structural models with micro-scale material details. The work focused on engineered microstructures that increase translaminar toughness in CFRP and graphene composites. Abaqus multi-scale capabilities, user subroutines, and mesh superposition techniques enabled accurate simulation of localized damage events such as impact and delamination.
Abaqus Explicit and Standard solvers support different length and time scales within one model
User subroutines and plug-in interfaces allow custom failure criteria and material models
Mesh superposition creates handshake regions between coarse macro meshes and fine micro meshes
Microstructure modifications raised carbon-fiber fracture toughness by 560 percent in tests
Simulation framework supports future nanoscale design of tailored mechanical properties
