1. 1. Adhesive bonding of fiber laminate patch to sandwich-structured composite

   University essay from Lunds universitet/Materialteknik

   Author : Daniel Nesic; [2022]
   Keywords : Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

   Abstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE

3. 2. Ground-nesting bees in the age of urbanization : quality of sandy habitat and wild bee diversity in Uppsala, Sweden

   University essay from SLU/Dept. of Ecology

   Author : Indre Cepukaite; [2022]
   Keywords : ground-nesting bees; wild bees; cleptoparasitic bees; indicator taxon; urbanization; sandy soil; bare soil; habitat age; ground cover; diversity; pollinator protection and conservation;

   Abstract : Wild bees are indispensable pollinators of most flowering plants and agricultural crops, and thus are vital components of functioning ecosystems and provide essential ecosystem services to humans. This study primarily aimed to discover the environmental features of nesting habitat that are mostly associated with wild ground-nesting and associated cleptoparasitic bee species diversity in urban landscape.

6. 5. Patch loading resistance of welded I-beams : with respect to misaligned web stiffeners

   University essay from KTH/Stålbyggnad

   Author : John-Alexander Boutzas; Dafina Zeka; [2016]
   Keywords : Patch loading; Stiffeners; I-beam; Plated steel structures; Abaqus; Simply supported beam;

   Abstract : When a concentrated load is introduced perpendicular to the flanges of a steel beam, this condition is referred to as Patch loading (Gozzi, 2007). This occurrence is common in many steel structures, for example at supports or during launching of bridges. READ MORE
