Mathematical modeling of visco-elastic-plastic deformation in capillary-porous materials in the drying process

In the paper there is described solving a current scientific problem of mathematical modeling of heat-mass transfer processes and elastic-viscous-plastic deformation taking into account the mechanics and sorption creep in hygroscopic capillary-porous materials with variable anisotropic heat and mechanics characteristics what is of importance for the rational choice and substantiation of energy conservative technologies of timber drying under the conditions of necessary qualitative production providing. There has been implemented the formulated mathematical model of timber deformation during the drying process which enables to identify two-dimensional intense-deforming state under the conditions of non-isothermal humidity transfer by means of the finite elements method (FEM). This method has been developed for the research of the two-dimensional anisotropic intense-deforming state during the capillary-porous materials drying process in an elastic-viscous-plastic area of deformation taking into account the mechanics and sorption creep. There has been elaborated the applied software which consists of the documented classes and provides the possibility to automate the finite-elemental analysis of timber intense-deformation state during drying process.
