Project description
Third-cycle subject: Solid Mechanics.
Solid Mechanics can be regarded as a link between materials science and applied mechanics, with emphasis on the latter and emphasis on computational methods, fracture mechanics, mechanics of materials.
In the current project, focus will be on developing a model for of ductile fracture in heterogeneous steels that has been subjected to time-dependent ageing and degradation mechanisms. Ductile failure is primarily an outcome of nucleation, growth and coalescence of voids. Here, the possible influence of nano-sized micro-voids, weakened grain boundaries and pre-existing defects in the micron/milli-metre range will be investigated. The research is fundamental and involves nonlocal continuum theory, numerical analysis with intrinsic material length scales, and verification by experimental work. It is interdisciplinary with connections to material science as microstructural changes that influence the ductile failure mechanism must be considered. Fracture properties affected by ageing phenomena must be addressed in many industrial applications, as for instance in nuclear, process and aerospace industry.
A suitable background would be a Master of Science in Engineering Mechanics.
Supervision: The doctoral student will be supervised by: Professor Jonas Faleskog and Lecturer Professor Pål Efsing.

Information regarding admission and employment
Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
