In situ Longitudinal Tensile Tests of Pine Wood in an Environmental
Scanning Electron Microscope
Summary
To study wood fracture on its cellular level, small tensile specimens of pine (Pinus sylvestris [L.])
were fractured in situ in tension inside the chamber of an ESEM (Environmental Scanning Electron
Microscope). Fractured surfaces of macroscopic tensile test specimens were also studied with
an ESEM. The same kind of fracture phenomena were observed in both small and large specimens.
The in situ tests proved to be reproducible and the results revealed typical fracture propagation0
directions and order in softwood under longitudinal tension. The gradual change of material
properties of wood in the radial direction was found to strongly influence the fracture process.
