  1. 1. 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

  3. 2. Basic Creep of Young Concrete - Sensitivity in the Evaluation Method

    University essay from KTH/Betongbyggnad

    Author : Benar Ekmat; Natalea Hermes; [2019]
    Keywords : thermal cracking; young concrete; creep; Linear Logarithmic Model; temperature development; average strain; sensitivity.; Temperatursprickor; ung betong; krypning; Linjär Logaritmisk Modell; temperaturutveckling; töjning; känslighet.;

    Abstract : Creep is defined as deformation that takes place under constant load after an initial elastic response. This thesis focuses on a material property problem area that concerns stress analysis. Focus is on stress development considering creep deformations occurring when a concrete structure is under load, i.e. READ MORE

  4. 3. Experimental analyses on XLPE under tension and compression

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : faranak pirnia; [2014]
    Keywords : XLPE; stress relaxation; compressive; tensile; visco elastic models; Young modulus stress.;

    Abstract : Cross linked poly ethylene used in high voltage cables insolation, has been studied to define its mechanical behavior. Time dependent deformation tests (stress relaxation) in three different strain levels and normal compressive and tensile tests were carried out. READ MORE

  5. 4. Determination of viscoelastic properties of adhesives

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Patrik Karlsson; [2014]
    Keywords : Adhesives material; Tension test; Stress; Strain; Viscoelastic; Timber; Glass;

    Abstract : A research project at Linnaeus University focuses on optimizing theadhesives joints between wood and glass, with the aim of obtain stiffcomponents that can act as a load and stabilizing elements and still betransparent. But there is, however, still a lack of knowledge regarding theadhesive materials which need to be further investigated. READ MORE

  6. 5. Adhesives for Load-Bearing Timber-Glass Elements : Elastic, plastic and time dependent properties

    University essay from Linnéuniversitetet/Institutionen för bygg- och energiteknik (BE)

    Author : Kent Phung; Charles Chu; [2013]
    Keywords : Monotonic tension test; cyclic test; relaxation test; adhesive; 3M DP490; SikaFast 5215; maximum strength; stress; strain; brittle; ductile; elastic; plastic; E-modulus;

    Abstract : This thesis work is part of an on-going project regarding load-bearing timber glass composites within the EU program WoodWisdom-Net. One major scope of that project is the adhesive material between the glass and timber parts. READ MORE
