Abstract
This thesis presents a finite element solution to the problem of swelling inclusions inside a host matrix. The FE simulations aim to mimic the behaviour of hydrides nucleating and growing inside a zirconium body with a heat expansion analogy, this is done with both a multi-step and single step technique carried out in the commercial FE software ABAQUS. The model mesh was generated with a Python script and a user subroutine *UEXPAN governed the heat expansion analogy. The user subroutine was written in the FORTRAN programming language. The goal with the simulations is to better understand swelling hydride inclusions, in particular so called blisters, and how they affect the mechanical state of their surroundings.
