SHEAR YIELD STRESSES AND FRACTURE TOUGHNESS OF SCOTS PINE (PINUS SYLVESTRIS L.) ACCORDING TO THE RAW MATERIAL PROVENANCE
Abstract
In this paper values of the fracture toughness and of shear yield stress in the shear zone of Scots pine are presented. Tests of cutting were carried on samples of Scotch pine (Pinus sylvestris L.) wood of five provenances from Poland. These experimentally cutting tests were carried on the sash gang saw PRW-15M and the values of cutting power were obtained. The values of fracture toughness and shear yield stress based on Atkins’s model for cutting power and using a methodology developed by Orlowski were determined from the values of cutting power. The diversity characteristic properties of Scots pine according to the raw material provenance are shown. The obtained values of fracture toughness and shear yield stresses of Polish pine wood could be used in computations of energetic effects of sawing on sash gang saws, and bandsaw machines with higher accuracy because raw material provenance is taken into account.
