Phase field modeling of ductile fracture in metals using the FEniCS open-source software
Fabio Di Gioacchino | fdigioacchino@mines.edu
Fracture mechanics is the fundamental field of solid mechanics concerned with the study of the initiation and propagation of cracks, which may lead to the catastrophic mechanical failure of components in service. Phase field modeling, developed initially to simulate phase transformations, has been recently employed to solve longstanding issues in the finite element formulation of fracture mechanics problems.
The goal of the project is for the student to test the predictive ability of the phase-field model of ductile fracture that has already been implemented at CSM using the open-source FEniCS software. This will be done by comparing numerical simulations with benchmark experimental observations, such as those reported in the so-called “fracture challenges” by the Sandia National Labs (resources are provided).

– Preferred. Have attended a course on the finite element method.
Time Commitment
20 hours/month
Skills/Techniques Gained
The student will gain hands on expertise with solving complex multi-physical problems by programming finite element calculations. This skill is increasingly important in academic research and industry.
Mentoring Plan
– I will give an initial powerpoint presentation of the scope and aims of the project. Go through the basics of FEM and the FEniCS software
– Weekly meeting to discuss progress and analysis
– Help the student in reporting his/her results.
