Relationship between Strain and Heat Generation
during Lateral Compression of Wood

In order to clarify the relationship between the deformation and the heat generation of wood, small specimens of Hinoki and Western Hemlock with circular notches at each radial face were compressed radially and the relationship between the average strain and the heat generation per unit time per unit volume at the bottom of notches, 2 mm high, was examined. Furthermore the end face of a specimen was microscopically observed immediately before and after the beginning of heat generation to examine the mechanism of heat generation during deformation of wood.
