3 PhD Research Fellowships at the Department of Structural Engineering (IVT-18/09)

The Department of Structural Engineering announces 3 positions as
research fellows. The department has at present 21 professors, 7
adjunct professors, 3 in other academic positions, 3 adjunct associate
professors, and 50 research fellows.
The employment period is 4 years, and the positions are within these 4 core areas at the department:

Biomechanics:
Development of a physiologically based decision making tool for
vascular network intervention. Essential for the tool will be the
development and implementation of a numerical model (using .e.g. the
finite-element method), accounting for wave propagation phenomena and
distributed mechanical properties. Based on biomechanical principles
and patient-specific imaging data, the model may predict the
hemodynamic impact of various interventions.

Structural mechanics:
The purpose of this study is to develop computational strategies for
multiscale modeling of structural components made of heterogenous
materials. A general approach to account for the effect of the material
substructure in constitutive modelling is to carry out computational
homogenization on a representative volume element (RVE). This approach
presumes complete scale separation such that the subscale solutions
interact only via their homogenized results on the macroscale,
typically via equilibrium of macroscale stresses. Multiscale modelling
can be used to identify material parameters of the material
microstructure. This will have a large impact on calibration of
material models and enable damage modelling in granular as well as
metallic materials.

SIMLab:
Field of research: Forming of materials.
In order to satisfy strict environmental requirements, lightweight
materials such as aluminum are attractive as components in vehicles.
Computer simulations are used today in order to optimize the forming
processes that are used in the production of safety components such as
bumper systems. During forming, the material is exposed to complicated
load situations that can lead to strain localization and fracture.
Models for material and fracture will be examined/validated with
emphasis on non-proportional loading. The study will include laboratory
tests in a recently acquired test machine and finite element analyses.

Concrete structures:
Numerical simulation of concrete structures and other hybrid structures
in different time- and construction phases. Current topics are
modelling of time depndent material properties, interface between
different materials, degradation of materials, and time dependent
changes of structural models.

Applicants should have the minimum qualification of an
internationally recognized master’s degree or equivalent. For all the
positions a background within the field of technology, physics, and
mathematics will be suitable.
