Deformation behaviour of particle-strengthened alloys: a Voronoi mesh approach

A modelling approach based on the discretisation of a particle-strengthened material using a Voronoi mesh is considered. The model is applied to studying the effects of particle arrangement on the deformation behaviour of a particle-strengthened alloy, particularly on its creep resistance. On a local scale, i.e. within an individual Voronoi cell containing a single particle, a dislocation density-based constitutive model developed previously is …
