11. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment
Sammanfattning : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. LÄS MER
12. Compressive failure of unidirectional NCF composites
Sammanfattning : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). LÄS MER
13. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure
Sammanfattning : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. LÄS MER
14. Wellbore stability analysis based on a new true-triaxial failure criterion
Sammanfattning : A main aspect of wellbore stability analysis is the selection of an appropriate rock failure criterion. The most commonly used criterion for brittle failure of rocks is the Mohr-Coulomb criterion. LÄS MER
15. Explosions in urban environments: Modelling of gas explosions and risk of premature shear failure in reinforced concrete structures
Sammanfattning : The risk for accidental gas explosions in urban environments has increased in Sweden in recent years. This is due to densification of existing urban centres and the rise of vehicles powered by alternative fuels. LÄS MER
