Description of Creep of The Lignostone in Biaxial Stress States

M. Czech

Poland

The results of creep investigations of the beech-wood lignostone specimens cut along the grains are presented. In the two-dimensional stress state the shearing stress is kept constant while the tensile stress varies. The description of creep of the lignostone as a nonlinear and orthotropic material is proposed by means of the equations [...].This description has been found to be satisfactory.
