Abstract

The changes occurring in wood when it is subjected to compression straining in well-defined directions have been studied. The straining has also included dynamic (oscillations at frequencies up to 84 Hz.

The changes occurring in the wood have been determined by measurement of the resulting permanent strain of the wood specimens. Fiber damage has been evaluated by measuring the intrinsic viscosity of the pulp after a standardized sulfite delignification. Some microscopic examinations were also carried out.

The compressions were carried out either parallel to or perpendicular to the gram on air-dry or water-saturated specimens. The energy consumption during the compression treatments has also been considered.
