1. 16. FE Modelling Of Two Femur Fixation Implants

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Ali Arsiwala; Vatsal Shukla; [2021]
   Keywords : FEM; Femur; Image Segmentation; Material Modelling; Recon Implant; Antegrade Implant; Atypical Femoral Fracture; Intermedullary Nail;

   Abstract : In the pool of women over the age of 50, the likeliness of an atypical fracture increase drastically, partly due to osteoporosis. With a pre-existing implant in the femur bone, inserted due to a prior atypical fracture, treating a later femoral neck fracture is complex and risky. READ MORE

3. 17. Life and fracture in very high cycle fatigue of a high strength steel

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Daniel Karlsson; [2021]
   Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

   Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE

4. 18. FE-Modelling of a Joint for Cross-Laminated Timber

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Linus Ekhagen; [2021]
   Keywords : cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

   Abstract : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. READ MORE

5. 19. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Nitin Narayanaswamy; [2020]
   Keywords : Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

   Abstract : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. READ MORE

6. 20. Correlation of numerical simulation methods and failure criteria to experimental burst test

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

   Author : Karlo Kasljevic; [2020]
   Keywords : Gas; Rotor; Turbine; Overspeed; Burst; Test; Strength; Analysis; Failure; Criteria; Burst margin; Stress analysis; Finite element method; Rotating disc; Burst Strength; Turbine disc; turbo-engine disk; Fracture; Blisk; Correlation study; Technology and Engineering;

   Abstract : Predicting the burst speed of turbine rotors is a costly and challenging task. Therefore, the scope of this thesis is to perform a correlation study between numerical simulation methods and failure criteria to experimental over-speed burst test of the Prometheus turbine rotor.
