The aim of the project will be to study the effects of biochar on physiology, growth, and vitality of urban trees. The work includes soil and biochar analyses and physiological measurements of saplings and mature trees. The project will be a part of Rest till Bäst (biokol.org) and the experiments are included in the larger aim of that project. The position is a research position with the possibility to be involved in teaching and supervision at bachelor and master levels if the successful candidate is interested.

Qualifications
To become eligible for this position the applicant needs to have a doctoral degree in forestry, urban forestry, plant ecology, ecophysiology, plant physiology, soil science or equivalent. Further, the candidate needs to present documented scientific skills in the subject area described and the ability to communicate science in English is required.

Location: Växjö

Start: September 1st, 2022, or by agreement

Work description

The project is about establishing models and produce experimental data related to shape stability of wood or wood-based materials. The shape stability of wood is primary dependent on mechanical loading, changes in moisture content due to wetting or drying and the temperature. The model for shape stability should be based on an extended continuum approach for materials that can be categorized by consisting of different phases, e.g., dry solid, vapor and liquid water phases in wood. The model of interest in this project is the Hybrid Mixture Theory, HMT. In the project the HMT should be extended to also include fracture development in wood by using the concept of the Phase-field Fracture Model, PFM. The PhD student will work together with the supervision team and, among other things, do the following: 

  • Learn the basics of continuum mechanics including constitutive modelling.
  • Learn how thermodynamics is used in continuum mechanics to define constitutive functions.
  • Learn the basics and underlying theories leading to the HMT approach.
  • Learn the basics of large deformation mechanics and learn how deformation gradient splitting approaches related to swelling strains can be established.
  • Learn the basics of FEM formulations including transient and dynamic systems.
  • Learn the basics of fracture mechanics and especially learn the theory behind PFM.
  • Learn how to establishing your own program codes for advanced FEM simulations including strongly coupled, transient and non-linear features.
  • Learn about the microstructural properties of wood and how these properties relate to the mechanical behavior at macrolevel.
  • Learn how to operate experimental equipment for measurement on shape stability of wood exposed to drying etc.

In the project the PhD student should gain knowledge and produce novel teoretical and experimental results in the following areas:

  • Modelling of shape stability by using the approach of HMT and establishing FEM formulations based on large deformation mechanics for swelling materials.
  • New knowledge should be established on how PFM can be integrated into HMT.
  • Produce experimental data which should be used to verify the material parameters oft he established models.
  • Implement models and test results to increase industrial utilization of wood materials and to propose new competitive and environmentally friendly wood building construction solutions.

The project is mainly about theoretical studies about wood and wood-based materials, applied mathematics (continuum mechanics), FEM modelling and its coding but also experimental studies will be included. The studies is to be performed in close cooperation with the supervision team at Linnaeus University and local companies that are expected to take advantage of the new opportunities.
