6. Multiphysical analysis methods to predict the ageing and durability of concrete
Sammanfattning : With the societal demand for sustainability and the increasing age of infrastructure, a crucial task for the civil engineering community is to improve the durability of concrete structures. This thesis aims to contribute to such development through theoretical studies using mathematical modelling and numerical simulations. LÄS MER
7. Cracking in Reinforced Concrete Structures Due to Imposed Deformations
Sammanfattning : This thesis is concerned with modeling of the cracking process in reinforced concrete due to imposed deformations. Cracking is investigated both at early ages, during hydration, and at mature age when the final properties of the concrete are reached. LÄS MER
8. Crack growth and development of fracture zones in plain concrete and similar materials
Sammanfattning : [abstract missing].... LÄS MER
9. Multiscale Modelling of Reinforced Concrete Structures
Sammanfattning : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.

10. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses
Sammanfattning : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. LÄS MER
