heat treatment - Opis:
- The technological process of thermal treatment of capillary-porous materials, characterized by the influence of several factors on the material as load, humidity and temperature was considered. Mathematical models of non-isothermal moisture transfer and viscoelastic deformation, taking into account the fractal structure of the environment were constructed. One-dimensional mathematical models of deformation-relaxation processes in environments with fractal structure characterized by the effects of memory, spatial nonlocality and self-organization were considered. Taking into account that the fractional parameters of fractal models allow us to describe the deformation-relaxation processes in comparison with traditional methods more fully, the optimal approximation method, the Proni’s method was proposed. This method allows us to reduce the problem of identification of the fractional parameters which are part of the creep and relaxation kernels structure, to finding the solutions of systems of linear equations. Software to implement the obtained models was developed.
