1. Modelling of Concrete Subjected to Cyclic Loading
Sammanfattning : The infrastructure of today depends heavily on concrete structures. Most of these structuresare subjected to repeated loads, known as fatigue or cyclic loads: the loads weakenthe structure. As this phenomenon is of high cost to society, a deeper understanding ofthe deterioration process of cyclic loading would be beneficial. LÄS MER
2. Excess pore water pressure generation in fine granular materials under cyclic loading -A laboratory study
Sammanfattning : Abstract Excess pore water pressure can be generated in subgrades of both railway and pavement sub-structures under cyclic loading caused by heavy traffic. When saturated subgrades are subjected to cyclic loading, excess pore water pressures accumulate over time which then could lead to migration of particles into overlying layers. LÄS MER
3. From Macromolecular Design to Supramolecular Self-assembly
Sammanfattning : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

4. Concrete Structures Subjected to Blast Loading
Sammanfattning : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. LÄS MER
5. On cyclic accumulation models for degradation of railway foundations
Sammanfattning : The degradation of railway foundations due to the repeated loading of traffic induces maintenance and safety obligations for the track operator. One major contributor to track degradation is the accelerated settlement rates in soft soils below the track that lead to alignment issues, especially at stiffness transitions. LÄS MER
