11. Bacteria - based self - healing mortar with bio - plastic healing agents : Comparative analysis on quantification and characterization of self-healing by various experimental techniques
University essay from KTH/BetongbyggnadAbstract : Crack formation in concrete structures due to various load and non-load factors leading to degradation of service life is very common. Repair and maintenance operations are, therefore, necessary to prevent cracks propagating and reducing the service life of the structures. READ MORE

12. The impact of stage casting on shrinkage restraint in concrete walls
University essay from KTH/Byggteknik och designAbstract : The most used widely material in the construction and industrial industry is concrete. Concrete is a material that has been used for a long time and will remain to do so. Therefore, it is especially important to obtain knowledge of the material’s properties and how it is affected by various conditions. READ MORE

13. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics
University essay from KTH/MaterialvetenskapAbstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE

14. Numerical analysis of paperboard delamination using cohesive elements
University essay from KTH/HållfasthetsläraAbstract : A new test method for measuring the shear strength associated with mode III delamination of paperboard is studied with the purpose of reducing the size of the test configuration. The method, which uses a split cantilever beam (SCB) specimen, measures the shear strength indirectly through the fracture resistance. READ MORE

15. Cracking in a slender concrete slab due to thermal variation
University essay from KTH/BetongbyggnadAbstract : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. READ MORE
