Summary: THE GOAL OF THE RESEARCH ISCONTRIBUTION TO THE FINDINGS OFRHEOLOGICAL PROPERTIES OF THE WOOD. GREAT DEMANDS FOR RACIONALUSING OF WOOD FIND THEIR ANSWER IN DOMAIN OF RHEOLOGICALPHENOMENS. MATHEMATICAL PRESENTATION OF CREEP OF THE WOOD THROUGHTHE CERTAIN PERIOID OF TIME IS DEFINED BY RHEOLOGICAL MODELS OFWOOD. RHEOLOGICAL MODELS ARE OPERATED, BESIDE OTHERS, BYCOEFFICIENTS OF VISCOSITY WHICH DEPEND ON NUMEROUS FACTORS, SUCHAS TEMPERATURE OF WOOD, HUMIDITY OF WOOD, ETC. IN THE RESEARCHWILL BE GIVEN CONTRIBUTION TO THE FINDINGS OF DEFORMATION SHAPEOF LAMINATED WOOD UNDER SHORT-TERM AND LONG-TERM LOAD.CONTRIBUTION TO THE ESTABLISHING COEFFICIENTS OF VISCOSITY OF THEWOOD AND VARIOUS FACTORS WILL BE GIVEN.

Keywords: WOOD, RHEOLOGY

Research goals: RHEOLOGY IS NEW SCIENTIFIC DISCIPLINE WHICH RESEARCHES CREEP PROBLEMS AND MATERIAL DEFORMATIONS WHICH ASSUMES RELATIONSHIP BETWEEN STRESSES AND DEFORMATIONS IN ELASTIC AND PLASTIC AREA. EXPERIMENTS SO FAR SHOWN GREAT DIFFERENCES BETWEEN BEHAVIOR OF THE WOOD UNDER LONG-TERM AND SHORT-TERM LOAD. THE GOAL OF THE RESEARCH IS CONTRIBUTION TO THE FINDINGS OF THESE RHEOLOGICAL PROPERTIES OF THE WOOD. ESTABLISHING THE COEFFICIENT OF VISCOSITY OF LAMINATED WOOD IS EXPECTED.
