  1. 6. Wood and moisture-induced strains in a large deformation setting in 3D

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Fredrik Ström; Anwar Obeido; [2022]
    Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

  3. 7. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

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

    Author : Emil Nilsson; [2021]
    Keywords : CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

    Abstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

  4. 8. Stability of building structures using NLFEA including second order effects : Applications with the software ATENA-GiD

    University essay from KTH/Betongbyggnad

    Author : Alexandros Petkoglou; [2021]
    Keywords : Non-linear analysis; second order effects; prefabricated buildings; ATENA; GiD; slip connection; Icke-linjär analys; andra ordnings effekter; förtillverkade byggnader; prefabricerade byggnader; ATENA; GiD; glidkoppling;

    Abstract : In Sweden, prefabrication in the construction industry is a very common system. In prefabricated structures, there are various kinds of connections and generally many hinged connections. Therefore, it is of high interest to study the behavior of the prefabricated buildings in relation to the connections. READ MORE

  5. 9. Industrial Requirements for Cross-Laminated Timber Manufacturing

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Matilda Torneport; [2021]
    Keywords : Cross-laminated timber; CLT industry; Wood species; Adhesive; Strength class; Timber grades;

    Abstract : Wood is a valuable sustainable material that meets the requirements for structural application. Cross-laminated timber (CLT) is a wood-based product that is mainly used in the building industry. Due to the rapid global market increase, a number of new CLT plants are emerging worldwide and thereby a need for standardisation is more than ever. READ MORE

  6. 10. Investigation of elastic powder properties using analytical powder decompression : Effects of tablet compaction parameters, pressure, speed, and lubrication

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Pardis Babaei; [2020]
    Keywords : Pharmaceutical powder; elastic powder properties; analytical powder decompression;

    Abstract : Aim: The objective of this project was to use analytical powder decompression (APDC) in tablet compaction processes to study the elastic behavior of powders. Background: During powder compaction, the particles undergo four stages of rearrangement, plastic deformation or particle fracture, and elastic deformation. READ MORE
