1. 16. Strain Rate Effect on Fracture Mechanical Properties of Ferritic-Pearlitic Ductile Iron.

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Firas Almaari; Essam Aljbban; [2018]
   Keywords : Ductile Iron; Dynamic Three Point Bending Test; Strain Rate; Fracture Energy.;

   Abstract : This study investigates the effect of strain rate on fracture properties of Ferritic-Pearlitic Ductile Iron. A series of dynamic three point bending tests, with various load application rates, are conducted on Charpy V-notch specimens, in room temperature and approximately -18 °C. READ MORE

3. 17. Investigation of Ductility Dip at 1000˚C in Alloy 617

   University essay from KTH/Materialvetenskap

   Author : Julia Sjöström; Helena Åkesson; [2017]
   Keywords : Ductility dip cracking; Ni-based alloy; tortuous grain boundaries; intergranular precipitates; grain boundary migration; superalloy; M23C6; Ti N; C ; solid state cracking; dynamic recrystallization;

   Abstract : Alloy 617 displays a ductility dip during straining at exactly 1000˚C, leading to brittle fracture. A sudden decrease in ductility appearing during Gleeble hot ductility tests of Ni-based superalloys is a well-known phenomenon, while its cause is unknown. READ MORE

4. 18. A 4D Analysis of a Minor Graben Structure at Ekolsund, South Central Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Alexander Sehr; Andin Eric; [2017]
   Keywords : South central Sweden; pull apart basin; 3D brittle deformation model; reactivation; striation markers; Södra centrala Sverige; pull apart basin; 3D spröd deformationsmodell; reaktivering; striation markörer;

   Abstract : The objective of this project is about a kinematic analysis of a shear zone, specifically a graben structure. The surface of the study area has also been investigated, this is to understand if a faulting reactivation has occurred due to glacial impact. READ MORE

5. 19. Analysis and Design of an Adhesive Joint in Wind Turbine Blades

   University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

   Author : Jonatan Pettersson; [2016]
   Keywords : Wind Turbine Blade; Adhesive; Fracture mechanics; Carbon Fibre; Technology and Engineering;

   Abstract : The demand for renewable energy is constantly increasing and in order to compete with other sources of energy the wind energy output has to increase. The power output from wind turbines are highly dependent on the swept radius of rotor blades. READ MORE

6. 20. Reinforced Concrete Beams Strengthened with Side Near Surface Mounted FRP : A parametric study based on finite element analysis

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Rewan Eredini; [2016]
   Keywords : Side near surface mounted reinforcement; Bottom near surface mounted reinforcement; Parametric study; FEM-analysis; Atena; Carbon fiber reinforced polymer;

   Abstract : Most of the today’s concrete structures are older than tenyears, and the need to strengthening existing structures is growing steadily. This is due to various reasons such as degradation due to ageing, environmentally induced degradation, poor initial design or construction and lack of maintenance, to name a few. READ MORE
