1. 16. Fracture analysis of tensile- and fatigue failure for perforated and wedge wire structures

   University essay from

   Author : David Barjosef; Alexander Austen Öhrn; [2022]
   Keywords : ;

   Abstract : In the effort to produce more durable filters and understand their mechanical failure, this study presents distinctive indicators on the cause of failure for welded perforated- and wedge wire sheets in 316L stainless steel, super duplex UR52N stainless steel and grade 2 titanium. The study achieves this by fracture analysis on specimens from tensile strength- and fatigue testing. READ MORE

3. 17. Analysis of Resin Impregnated Non-woven : In collaboration with Hitachi Energy

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Ahmed Abdulkareem Najm Al-Saedi; Anders Hedenfeldt; Andrea García; Anna-Karin Kron; Cornelia Bergström; Lova Källkvist; [2022]
   Keywords : resin impregnated non-woven; bushings; composite; resin impregnated paper; tensile; bending; permeability; mechanical properties;

   Abstract : High voltage bushings are the most critical components of power transformers. A common material used in bushings is resin impregnated paper (RIP). Hitachi Energy is investigating whether this can be replaced with a new material, resin impregnated non-woven (RIN). READ MORE

4. 18. Mechanical properties of WE43 : Finding optimized process parameters using PBF-LB for enhanced properties of the magnesium alloy

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Fanny Saarela; Fanny Sandblad; [2022]
   Keywords : biomedical engineering; materials science; additive manufacturing; powder bed fusion laser beam; PBF-LB; magnesium; magnesium alloys; WE43; mechanical properties; scan strategy; layer rotation; build direction; build orientation;

   Abstract : When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. READ MORE

5. 19. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Yusuf Qasem; Younes Chraibi Ottosson; [2022]
   Keywords : Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

   Abstract : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

6. 20. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

   University essay from Karlstads universitet

   Author : Hasan Majid; [2022]
   Keywords : ;

   Abstract : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. READ MORE
