  1. 11. Strain Rate Characterization of Packaging Materials

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Zichun Wang; [2022]
    Nyckelord :Paperboard; Strain rate; yield stress; Technology and Engineering;

    Sammanfattning : This master thesis firstly introduced the basic knowledge of packaging materials through a literature survey focused on exploring the effect of strain-rate on mechanical properties of paperboard materials. By means of tensile tests and microscopic observation, the changes of mechanical properties such as yield strength, strain and Young's modulus of the two different paperboards used in laminated packaging materials for the two different package types Tetra Fino® Aspetic (TFA) and Tetra Brik® Aseptic (TBA) from Tetra Pak® were analyzed at strain rate ranging from 0.

  3. 12. Småhusgrund med cementbundet rivningstegel

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Victor Andersson; Samuel Nilsson; [2022]
    Nyckelord :Cementbundet rivningstegel; Återvunnet tegel; Miljösmart betong; Tegelaggregat; Platta på mark; Småhusgrund; Technology and Engineering;

    Sammanfattning : Miljöpåverkan är ett ständigt återkommande ämne i samhällsdebatten. Många företag strävar efter att minimera sin miljöpåverkan, vilket kan ske genom att återanvända material i stället för att producera nya. I fallet med betongproduktion finns det flera sätt att göra den bättre för miljön. LÄS MER

  4. 13. Conditioned 3D-printed polyamides for structural optimization : Establishing the material data to advance in AM utilization

    Master-uppsats, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Philip Olsson; [2022]
    Nyckelord :Additive manufacturing; selective laser sintering; multi jet fusion; moisture; temperature;

    Sammanfattning : Polyamides are commonly used in additive manufacturing for final part production, but the material performance can be affected by environmental conditions. The purpose of this project was to evaluate the effects of moisture and temperature on 3D printed polyamides and how structural optimization can benefit from condition-specific data. LÄS MER

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

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Fanny Saarela; Fanny Sandblad; [2022]
    Nyckelord :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;

    Sammanfattning : 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.. LÄS MER

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

    Master-uppsats, Karlstads universitet

    Författare :Hasan Majid; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
