  1. 1. 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

  3. 2. 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

  4. 3. 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.

  5. 4. Study of delamination of composite hat skin stringer interface failure

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Rajkumar Rajamanickam; [2019]
    Keywords : Delamination; Cohesive Zone Model; Skin-Stringer; Composite modelling; ABAQUS; Interface failure;

    Abstract : The use of composite materials brought a tremendous breakthrough in the scientific world of aerospace engineering. The lack of understanding of the failure of composite materials can be disastrous. Composite laminated structures need to be thoroughly studied and investigated in the design stage. READ MORE

  6. 5. Numerical and experimental analysis of adhesively bonded T-joints : Using a bi-material interface and cohesive zone modelling

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap
