Bacterial decay in waterlogged archaeological compression wood varies with severity of compression wood

Holzforschung, 2022
Abstract Bacterial decay in compression wood (CW) tracheids of waterlogged archaeological wood (WAW) was investigated using light microscopy, confocal laser scanning microscopy, transmission electron microscopy (TEM), and TEM immunogold labeling.

Compressive fatigue in wood

Wood Science and Technology, 2000
An investigation of fatigue failure in wood subjected to load cycles in compression parallel to grain is presented. Small clear specimens of spruce are taken to failure in square wave formed fatigue loading at a stress excitation level corresponding to 80% of the short term strength. Four frequencies ranging from 0.01 Hz to 10 Hz are used.

Bearing stiffness in wood-to-wood compression joints

Engineering Structures, 2015
In post-tensioned timber frames beams and columns are connected by means of a tendon. The tendon presses the beams against the columns which leads to a stress situation where beams are loaded parallel to the grain and columns are loaded perpendicular to the grain.

Effective Thermal Conductivity of Compressed Woods

Heat Transfer: Volume 3, 2000
Abstract The total amount of lumbers consumed in Japan during a year, reaches to 1.1 billion cubic meter. However, 75 percent of them are imported. The resource of same 1.1 billion cubic meters is growing up every year in the domestic forest. This is due to the price difference between the domestic and imported lumbers.

Partial transparency of compressed wood

AIP Conference Proceedings, 2016
We have developed novel wood composite with optical transparency at arbitrary region. Pores in wood cells have a great variation in size. These pores expand the light path in the sample, because the refractive indexes differ between constituents of cell and air in lumen. In this study, wood compressed to close to lumen had optical transparency. Because

"WOOD MODEL" for the dynamic behaviour of wood in multiaxial compression

Holz als Roh- und Werkstoff, 2002
The use of wood as a shock absorber in containers for radioactive materials and the need of designers for good quality mechanical characteristics had lead us to investigate the behaviour of wood under multiaxial dynamic compression. This paper presents the main experimental results of the static and dynamic compression we performed on small samples of ...

Behavior of Wood in Transverse Compression

Journal of Testing and Evaluation, 1994
Abstract A finite element analysis program exists to evaluate the stress distribution in wood members subjected to perpendicular-to-grain (transverse) compression. In this study, the program was used to perform parameter studies to evaluate the effects of key variables on the distribution of stresses and the maximum stress concentrations

Modeling Wood in Transverse Compression

Journal of Testing and Evaluation, 1994
Abstract A plane-stress, Finite element model has been developed to predict the stress distribution in wood members subject to perpendicular-to-grain compression. This model exploits linearstrain, isoparametric triangular elements used in sufficient number to achieve a convergent solution.
