Multi-scale modelling of nuclear graphite tensile strength using the Site-Bond lattice model

Abstract:

Failure behaviour of graphite is non-linear with global failure occurring when local micro-failures, initiated at stress-raising pores, coalesce into a critically sized crack. This behaviour can be reproduced by discrete lattices that simulate larger scale constitutive responses, derived from knowledge of microstructure features and failure mechanisms. A multi-scale modelling methodology is presented using a 3D Site-Bond lattice model. Microstructure-informed lattices of both filler and matri...
