文摘
- •
Micro-CT imaging was applied to examine coke microstructure at high resolution.
- •
The 3D rendered microstructure was used as the input in finite element analysis.
- •
3D von Mises stress maps showed regions of high stress concentration in the coke.
- •
The coke was stressed to breaking point under mixed mode loading and imaged again.
- •
Correspondence between calculated and actual high stress points was demonstrated.
