1. Analytical and numerical approaches to estimate peak shear strength of rock joints
Sammanfattning : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. LÄS MER
2. Peak Shear Strength of Rock Joints – Towards a Methodology for Prediction Based on Field Data
Sammanfattning : The rock joint shear strength at field scale is an important design parameter and remains a challenge for rock mechanics engineers. In Sweden, there exist a large number of concrete dams that are founded on rock masses which in many cases contain sub-horizontal rock joints. LÄS MER
3. Mechanical behaviour of adhesive layers : experimental methods, cohesive laws, and fracture mechanics
Sammanfattning : Adhesive joining is today viewed as one of the key technologies to achieve decreased emissions in the automobile industry. To decrease weight, optimal material selection often results in different materials for different parts. This leads to the necessity to join mixed material. Here, the use of adhesives is the most promising joining technology. LÄS MER
4. Strength, fallouts and numerical modelling of hard rock masses
Sammanfattning : The prediction of compressive stress-induced failures is of concern for the design and construction of deep underground excavations in mining and civil engineering. An overstressed rock mass may result in fallouts of rock, which may cause occupational safety hazards, damage of equipment, and/or production disturbances. LÄS MER
5. Injectable Composite Hydrogels Based on Metal-Ligand Assembly for Biomedical Applications
Sammanfattning : This thesis presents new strategies to construct injectable hydrogels and their various biomedical applications, such as 3D printing, regenerative medicine and drug delivery. These hydrogels cross-linked by dynamic metal-ligand coordination bonds exhibit shear-thinning and self-healing properties, resulting in the unlimited time window for injection. LÄS MER
