  1. 1. Characterization methodology to assess the mechanical properties of delignified birch/PMMA transparent wood biocomposites

    University essay from KTH/Fiber- och polymerteknologi

    Author : Nicolò Arcieri; [2022]
    Keywords : Transparent wood; mechanical properties; fracture toughness; in situ experiments; cohesive zone model; Transparent trä; mekaniska egenskaper; brottsstyrka; in situ-experiment; modell för kohesionszonen;

    Abstract : Transparent trä biokompositer (TW) är en ny attraktiv klass av biokomposit. De är uppbyggda av delignifierat trä som impregnerats med en polymer med matchande brytningsindexet.  TW kan skräddarsys för inom ett brett spektrum av funktionella, optiska och mekaniska egenskaper.

  3. 2. Product Development and Finite Element Analysis of Polyurethane Press Shoe : Produktutveckling och finit element analys av press-sko i polyuretan

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Mikael Bergström; [2021]
    Keywords : FEM; Finite Element Analysis; Polyurethane Casting; PUR; Hyperelaticity; ABAQUS; Casting; Shoe Press; Press Shoe; Paper Making; Paper Machines; Tissue machine;

    Abstract : The press-section of a paper machine holds several different types of press rolls. One of the many press roll variants is the Valmet produced press roll, ViscoNip. This press roll utilizes an extended nip in order to increase the amount of water removed. READ MORE

  4. 3. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

    University essay from KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

    Author : Zeinab Mirzahassanagha; Eva Malo; [2021]
    Keywords : CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

    Abstract : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. READ MORE

  5. 4. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    University essay from KTH/Lättkonstruktioner

    Author : Mara Santaniello; [2020]
    Keywords : ;

    Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

  6. 5. Design of bi-adhesive joint for optimal strength

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Siva Koti Reddy Vennapusa; [2019]
    Keywords : Bi-adhesive joint; Linear elastic fracture mechanics; Cohesive zone modelling; Optimization;

    Abstract : To support the trust in the design development of adhesively bonded joints, it is important to precisely predict their mechanical failure load. A numerical simulation model with a two-dimensional linear elastic cohesive zone model using a combination of a soft and a stiff adhesive is developed to optimize the strength of a lap-joint.
