  1. 1. A Finite Element Study of the Shape Stability of Sawn Timber Subjected to Moisture Variations

    University dissertation from Lund : Lund Institute of Technology, Lund University, Division of Structural Mech

    Author : Sigurdur Ormarsson; [1995]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; deformation; wood; moisture; finite element method; Byggteknik; Civil engineering;

    Abstract : Shape instability in timber products exposed to moisture variation is a serious problem since it can make wood products unsuitable for construction purposes. In this thesis the finite element method has been used to simulate deformations during the drying process.….…. READ MORE

  2. 2. Numerical Analysis of Moisture-Related Distortion in Sawn Timber

    University dissertation from Göteborg : Chalmers University of Technology, Dep. of Structural Mech

    Author : Sigurdur Ormarsson; [1999]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Computer simulations; Deformation; Wood; Moisture; Drying; Finite element method; Byggteknik; Civil engineering;

    Abstract : A 3D theory for the numerical simulation of deformations and stresses in wood during moisture variation is described. The constitutive model employed assumes the total strain rate to be the sum of the elastic strain rate, the moisture-induced strain rate, the mechano-sorption strain rate and the creep strain rate.
