Problem or Industrial Need
CNT/polymer components can operate under changing temperature, requiring models that capture viscoelastic transitions and agglomeration effects.
Engineering or Scientific Solution
Two RVE formulations and finite-element analysis validated against dynamic mechanical testing.
Sebastian's Technical Contribution
Developed the computational models, performed formal analysis and software work, and connected predicted transitions with experimental measurements.
Methods and Tools Used
- Representative-volume-element development
- Temperature-dependent finite-element analysis
- Dynamic mechanical analysis in three-point bending
- Experimental-numerical comparison
Prototype, Simulation and Experimental Evidence
Two RVE models
Separate formulations represented dispersed and agglomerated nanocomposite behaviour.
DMA validation
Model predictions were compared with measured viscoelastic transitions.
Materials Today: Proceedings 2022
Peer-reviewed thermomechanical modelling study.
Measurable Result or Published Finding
Validated transition modelling
The models reproduced the principal temperature-dependent state transitions reported in the experiments.
Diagrams and Publications
Models are tested against experiments and returned to engineering decisions.
