Abstract

In paper, from positions of mechanics of a strained solid and contact problems of destruction necessity of development of mathematical model of pressing of an impregnated wood during its drying under pressure, within the limits of which is proved: affecting of forces of compression can be various by the nature and under the form of the press tool - flat, cylindrical, wedge-shaped and dot. Simultaneous pressing and drying demand the account in mathematical model of regularity of a straining of wood in a floor of heats on the basis of filtrational habits of dehydration of moisture-laden specimens; cyclic character of act of forces of a gauge pressure and the phases of an elastic and viscous and plastic straining of the specimens expelling their destruction caused by it, demand adequate conformity of time responses of a relaxation of dehydration and pressure in process of evolution of process of pressing and drying.
