Topic: Load deformation properties of the diseased hip capsule and
Project aim: This experimental study aims at assessing mechanically the load deformation
properties of the hip capsule ligaments in patients undergoing total hip replacement (capsular
removal) and those patients undergoing revision arthroplasty and to compare these to the
healthy state. It is hypothesized that hip capsules in patients with hip osteoarthritis and
neocapsules from patients undergoing revision arthroplasty have significantly altered mechanical

Topic: On the effects of surface coating and speckling of human skin and
esophagus samples

Project aim: This experimental study aims at investigating the chemical-physical effects induced
by the surface coatings on uniaxial load deformation properties of human skin and esophagus
specimens. It is hypothesized that solvent-based speckling causes increased stiffness, lowered
strain to failure and increased ultimate tensile stress as compared to an unspeckled state.

Topic: On the morphological and mechanical properties of the suspensory ligaments of the breast

Project aim: This experimental study aims at describing morphologically and mechanically the suspensory ligaments of the breast. It is hypothesized that suspensory ligament elasticity shows an agerelated change, and that load-to-failure decreases. The second hypothesis addresses sex
dependent difference in the morphology and mechanical parameters of the suspensory
ligaments. Post mortem computed tomography or magnetic resonance imaging will be conducted
before the suspensory ligaments are dissected in an anatomically embalmed state. Histological
analyses will substantiate the tissue composition of the suspensory ligaments. An additional
sample will be retrieved in an anatomically unembalmed state in from human corpses and
deployed for uniaxial mechanical analyses. Thorough knowledge on these structures will help
inform surgeons performing breast reconstructions to understand the mechanics of the breast
gland at different periods of life and differences between parity and sexes more extensive.

Topic: Mechanical and structural mapping of the human dura mater

Project aim and Methods: Dura mater samples will be taken from donors. The left hemisphere will be used to obtain samples in fibre and in cross-fibre direction on 6 different locations. These samples will be then tested mechanically under uniaxial tension in our biomechanics laboratory. Additionally, adjacent locations will be used to obtain samples for histological analysis as well as for multi photon microscopy. Collagen, elastin and cells in histological samples will be quantified using the software QuPath, whereas multi photon microscopy samples will be used to obtain the
collagen orientation throughout the thickness of the dura mater. This thesis will provide a detailed mechanical and microstructural mapping of the dura mater, which will yield new data for better and more detailed computational and physical models.

Topic: Influence of osmotic moisture content adaptation on the mechanical
characterization of biological soft tissues

Project aim: One parameter important to biomechanics is the moisture content of the tissue during testing as the degree of hydration can change material properties drastically. Osmotically active agents have been used to control moisture content prior to testing of soft tissue. The aim of this project will be to investigate the influence of different moisture adaptation protocols on the
mechanical characterization of soft tissues. The student will independently design and conduct experiments with human tissue samples. Several protocols for osmotic moisture adaptation will be tested and evaluated.

Topic: Bone density and load deformation properties resulting from Thiel
embalming OR On the suitability of Thiel embalming in bone biomechanics
Project aim: The aim of this given experimental study is to investigate whether Thiel embalming
related fixation effects cause morphological or mechanical alterations of human bone
composites derived from different anatomical regions. It is hypothesized that (A) cancellous
bone structure decreased as a time dependent variable of Thiel embalming exposition, and (B)
micro fragmentation of cortical bone, (C) resulting in increased bone stiffness and decreased
yield properties. Bone samples will be retrieved in a fresh and unembalmed post mortem state from the following regions: neurocranium, long bone, pelvis. Micro computed tomography scans and mechanical tests will be performed at different time points before and after Thiel fixation. Bone density, cortical and cancellous bone geometry and load deformation properties will be compared. The results of this study will help inform the community of biomechanicists on the suitability ofThiel embalmed bone for validation and surgical simulation tests.

Topic: On the load deformation properties of the sacroiliac joint ligaments – a cadaveric analysis

Project aim:
This experimental study aims at investigating the load-deformation properties of the extrinsic
(i.e., iliolumbar, sacrospinous and -tuberous) and intrinsic (anterior, interosseous, posterior)
sacroiliac ligament as well as the anterior and posterior longitudinal ligaments of the
lumbosacral transition and the obturator membrane. It is hypothesized that the ligaments have
site-dependent properties, contributing to the overall stability to different extent.
Pelvic ligaments will be retrieved from post mortem bodies in a fresh state and prepared for
mechanical testing following a standardized protocol established by our group. Uniaxial tensile
tests will be performed to determine the ligament (sub)structures. A thorough investigation appreciating the various attachment sites and orientations will help substantiate the role of the individual ligaments in pelvic stabilization.


Duration: 18 – 24 months, max. 16h /week                                                                                  Start: ASAP

Granular matter is extensively used in various industrial sectors. However, control and optimization of granulation systems pose significant challenges. This is since the mechanism of agglomeration and de-agglomeration is not well-understood. Therefore, in the GranSys-CG project, we focus on the fundamental investigation of wet particles interaction using multi-scale simulation approaches. In the framework of this project, we are hiring several Master’s students to validate and verify our models which are mainly implemented in OpenFOAM.
