“…Decrease in torque and twist was achieved by increasing the drying temperature and pre-steaming of the material prior to drying. The same relationship between torque and MC was confirmed in drying simulations using the finite element method (Ormarsson et al 1999) and in static climatic conditioning (Bäckström and Kliger 2006). …”

“…FEM was performed by means of the FE software (Abaqus 2008) based on special routines for wood distortion developed earlier by Ormarsson et al (1998Ormarsson et al ( , 1999. The routines take into account that wood is a moisture sensitive (cylindrical) orthotropic material concerning stiffness, shrinkage, and mechanosorption behavior.…”

“…It should be observed whether the discs are cracked and how is the crack development in the course of the drying process. The experimental disc samples will also be simulated by a 3D distortion model developed by Ormarsson et al (1998Ormarsson et al ( , 1999. The crack simulation by finite element modeling (FEM) in the present study is based on description of a cohesive crack model for wood.…”

“…Leavengood (2001) developed an Excel spreadsheet that estimates the dimensional change in wood with moisture loss (or gain) using a related approach, but does not provide an indication of cup magnitude. Ormarsson et al (1998Ormarsson et al ( , 1999Ormarsson et al ( , 2000 have developed a complex model that uses finite element simulations and considers mechano-sorptive and visco-elastic behaviors of drying wood that predict dimensional changes and warp, but this model is beyond the scope of the current, more pragmatic approach to estimating cup.…”
