Dataset on the mechanical behavior of rotary-cut veneer under tensile, compressive, and shear loading for the wood species European beech and birch

This dataset was created as part of the joint research project “Wood-based materials in mechanical engineering (HoMaba)”. The focus of the project was to enable wood and wood-based materials to be used in mechanical engineering applications. This was to be achieved by improving the predictability of their behaviour. To calculate and simulate wood-based materials (veneer composites), it was necessary to determine the basic mechanical behavior of veneer.

The dataset contains a total of 1188 data files within 60 test series for tensile, compressive, and shear tests on rotary-cut veneer. The following parameters were varied within the test series:

• wood species: European beech (Fagus Sylvatica L.)  and birch (Betula pendula Roth.)
• veneer thickness: 1, 2, 3 mm
• force direction: parallel to fiber direction, perpendicular to fiber direction (only for tension and compression)
• veneer surface coating: without (native) and coated with PRF-resin (220 g/m² per each surface; Dynea AS Aerodux 185)

The data files are located in the “01_Data” directory with categorized subdirectories. Each data file contains a header with descriptions of the following test parameters:

• wood species
• test type
• test conditions
  • force direction
  • measuring field length
  • measuring field width
  • temperature
  • relative humidity
  • testing speed
• specimen properties
  • surface coating
  • specimen length
  • specimen width
  • specimen thickness
  • density
  • moisture content

and followed by the measured stress-strain data with the following columns:

• stress_MPa: stress in force direction, tension and shear with positive sign, compression with negative sign
• stain: strain in force direction
• transverse strain: strain perpendicular to force direction, only for tension and compression

The “02_Results” directory contains two files with evaluated mechanical properties per test (results.csv) and as mean values per test series (results_mean.csv). The evaluated parameters are:

• modulus_MPa: Young’s modulus for tension and compression, shear modulus for shear test
• poisson: Poisson’s ratio, only for tension and compression
• ultimate_stress_MPa: maximum stress at failure
• ultimate_strain: strain at failure

A data paper describing the test methods used to determine the experimental data related to this repository is being submitted for publication.
