Job description

We invite applications for a PhD position in theoretical and computational modelling of fracture and damage of geomaterials. The overarching goal of this PhD project is to gain knowledge and understanding on the mechanics that governs the migration of magmatic intrusions towards the surface in volcanic plumbing systems. Two end-member models currently exist to describe the propagation of magmatic intrusions in the Earth’s crust. The hydraulic fracture model that describes the flow of magma into a brittle fracture that grows through a linear elastic host rock. The viscous indenter model that describes the ascent of magma by ductile deformation of the host rock. The PhD student will develop computational models to simulate the propagation of magmatic intrusions between these two end-members situations. Through a combination of theoretical and numerical work, the PhD student will quantify how inelastic processes in the rheology of the host rock affect the migration of magma. Overall, the PhD student will be trained to develop models of failure and damage in materials and will learn skills and knowledge directly relevant to other disciplines such as geophysics, material science and engineering.

The PhD student will be a member of the project “BEYOND ELASTICITY – How inelastic properties of crustal rocks control the propagation of dykes and sills in volcanic plumbing systems” funded by the Research Council of Norway. The project will be hosted at the Njord Centre, which is a research centre between the departments of Geosciences and Physics. Njord is one of the University of Oslo's main cross-disciplinary centers in Physical Sciences and Earth-related research.

The “BEYOND ELASTICITY” project will run as a collaborative effort between the Departments of Geosciences, Physics and Mathematics at the University of Oslo. The PhD student will be integrated in a multidisciplinary team of early-career scientists dedicated to study the dynamics of volcano plumbing systems from both geological, physical and theoretical approaches. The project will also benefit from collaboration with leading national and international research groups and institutions.

The PhD student will:

• Implement and run computational models to simulate the propagation of dykes and magmatic intrusions

• Investigate and quantify the impact of inelastic (plastic and viscous) deformation of the host rock on the migration of magma through the Earth’s crust

• Work in an interdisciplinary team combining expertise in geosciences, computational mechanics and the physics of solid and fluid

• Learn knowledge and skills directly transferable to other applications in geophysics or engineering
