1. 1. Micromechanical modelling of creep in wooden materials

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Oskar Falkeström; Kevin Coleman; Malin Nilsson; [2021]
   Keywords : Creep; RVE; Homogenization; Honeycomb; Tracheid; Comsol Multiphysics; Micromechanical modelling; Orthotropic; Parametric study; S2 material; Norwegian Spruce; Scots Pine; Cell geometry;

   Abstract : Wood is a complex organic orthotropic viscoelastic material with acellular structure. When stressed, wood will deform over timethrough a process called creep. Creep affects all wooden structureand can be difficult, time-consuming and expensive to measure. For this thesis, a simple computer model of the woodenmicrostructure was developed. READ MORE

3. 2. Mechanical characterization of DuraPulp by means of micromechanical modelling

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY); Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Mustafa Al-Darwash; Emanuel Nuss; [2015]
   Keywords : Natural fiber composites NFC ; Polylactic acid PLA ; Micromechanical modeling; Modulus of Elasticity MOE ; Shear modulus; Poisson’s ratio;

   Abstract : Södra DuraPulp is a relatively new eco-composite, made from natural wood fibers and polylactic acid (PLA), which comes from corn starch. Until now, there are only few applications for DuraPulp, mainly in the area of design. To find new fields of application, more knowledge about its mechanical material properties are of great interest. READ MORE
