1. Confined Compression of Single Particles : Development of a Novel Triaxial Testing Instrument and Particle-Scale Modelling
Sammanfattning : When predicting the performance of a powder compaction process, assessing the behaviour of the particles comprising the powder bed is of central relevance. Currently, however, no experimental methods are available for mimicking the multiaxial loading conditions imposed on the individual particles in a powder bed during compaction, and such analyses are therefore usually performed in silico.

2. Behaviour and modelling of a natural soft clay : triaxial testing, constitutive relations and finite element modelling
Sammanfattning : The main objectives if the research project have been to create an experimental basis for a more general theoretical modelling of Swedish clays and to improve the knowledge of the mechanical behaviour of natural soft clays. Another objective has been to investigate the effects of end restraint on the mechanical behaviour obtained in triaxial tests, by means of numerical simulations. LÄS MER
3. Analyses of Resilient Behavior of Unbound Materials for the Purpose of Predicting Permanent Deformation Behavior
Sammanfattning : Post compaction is the unintended compaction of the unbound material that commences immediately after a road is brought into service and caused by densification of the material. Analogies to this post compaction can also be seen in laboratory and field tests. LÄS MER
4. Analysis of Response and Development of Permanent Deformation of Unbound Granular Materials Using a Testing Box Technique
Sammanfattning : The main objective of this thesis is to study the response and development of permanent deformation in unbound granular materials, theoretically and experimentally. A testing box technique is used here to more closely simulate the behaviour of unbound aggregates subjected to external vertical loading. LÄS MER
Sammanfattning : Silt and sulphide soil are two types of soil which are dominating in northern Sweden, especially in the coast area of the Baltic sea. The stress-strain and strength characteristics of these two soils have so far not been as much explored as those for e.g. Scandinavian clays. LÄS MER
