Modelling Discrete Dislocation Dynamics with Discontinuity-Enriched Finite Element Analysis

Discrete Dislocation Dynamics concerns the analysis of microplasticity in which the dislocations, a line defect in the crystallographic periodicity, are treated as separate moving entities inside an elastic continuum. This analysis at the mesoscale can give valuable insights in the nature of dislocations and the behaviour of macroscopic...

Sea ice subjected to cyclic compression: Laboratory experiments and a dislocation based model

Wave or vehicular action on an ice sheet as well as structural vibrations and thermally induced loading cause cyclic loading on an ice sheet. To better understand the effects of cyclic loading on the strength of sea ice, cyclic loading tests have been conducted at the University Centre in Svalbard (UNIS). In addition, the corresponding ice...

Precipitates on Dislocations: Mathematical modelling of nucleating and growing precipitates on dislocations

Many models for nucleating and growing precipitates have been developed. Each model with their own advantages and disadvantages. Only few of those models are made for heterogeneous nucleation (on dislocations) and most of them are based on the mean radius approach. In the literature study by Vonk (2016) one of these models (by Zurob et al. (2002...
