Coupled-volume multi-scale modelling of quasi-brittle material

Multiscale failure modelling of quasi - brittle materials

Multi-material adaptive volume remesher

We propose a practical iterative remeshing algorithm for multi-material tetrahedral meshes which is solely based on simple local topological operations, such as edge collapse, flip, split and vertex smoothing. To do so, we exploit an intermediate implicit feature complex which reconstructs piecewise smooth multi-material boundaries made of surface patches, feature edges and corner vertices. Fut...

Material Properties of Brittle Bones

INTRODUCTION Osteogenesis imperfecta (OI) is a genetic disorder of type I collagen that results in bone fragility. This fragility is believed to stem from a combination of bone mass deficiency and compromised bone material properties [13]. Little data, however, is yet available to describe bone material properties in individuals with OI. This study presents the first characterization of bone ma...

Dynamic Fragmentation of Brittle Solids: A Multi-Scale Model

Multi-scale Modelling of Sintering

Sintering models at the atomistic, particle and component scales are briefly reviewed and problems in the current generation of sintering models are highlighted. A strategy of multi-scale modelling is proposed and our progress in the multiscale modelling is reported. Mathematical details of the models are left out and the paper is set out to demonstrate what is possible in the next generation o...
