Project: Development of particle based methods for granular flows and wear of tools during rock drilling


Granular materials are present in alot of areas and the modeling of its behavior is a complex task. My research concerns the development of particle-based models of granular materials, e.g. rock and soil, and its interaction with the drill bits. This involves fluid-structure interactions (FSI), large deformation, abrasive- and impact wear, coupling with CFD for transportation of drill cuttings and characterization and validation of constitutive models.

Project goals

As a part of my doctoral thesis, I am working on the GeoFit project. The goals for my involvement in the project are:

  • Develop and demonstrate modelling strategies based on particle based methods and finite element methods of the drilling and excavation process. This involves the characterization, calibration and validation of the constitutive- and wear models.
  • With the use of the numerical model: predict the performance of the drill bit in terms of wear, pressure distribution and vibrations in the adjacent soil and rock.
  • ​From the performance prediction: improve the drilling parameters, tool performance and material selection for different requirements in order to reduce tool damage and maintentance.
