1. Composite Bridges : Innovative ways of achieving composite action
Sammanfattning : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. LÄS MER
2. Construction of Composite Models from Large Data-Sets
Sammanfattning : Most processes of realistic complexity cannot be described by simple linear relationships. In this thesis we describe a method of how to construct composite models from observed data. It is assumed that the dynamics of the process changes with som 'operating-point vector', which is assumed to be a measurable quantity. LÄS MER
3. Pharmacometric Investigations of Prediction Precision and Advances of Models for Composite Scale Data
Sammanfattning : Clinical trials are needed to evaluate new treatments. In late-stage clinical trials, failures are mostly due to lack of efficacy. Fit-for-purpose analysis methods will likely increase the success rates and advance drug development by providing higher precision to support decisions such as go/no-go, dose selection, or sample size.

4. Analysis of transverse composite cross-ply laminates
Sammanfattning : Advanced polymer composites are commonly based on thin prepreg plies stacked at different angles to form a laminate. When the laminate is loaded, intralaminar transverse cracking in off-axis plies is one of the first damage modes. In the presented thesis, cross-ply laminates are used to study the transverse cracking phenomenon. LÄS MER
5. Damage accumulation and stiffness degradation in composite laminates
Sammanfattning : In the presented thesis analytical modeling of elastic properties degradation and modeling of damage evolution in composite laminates is performed. Transverse cracking initiation on a fiber/matrix level is briefly studied by testing model composites and cross-ply laminates. LÄS MER
