The subject of this paper is the control of computer-simulated drying processes far the purpose of their optimization. The simulated processes are carried out in such a way that the drying-induced stresses never exceed the stress limit. This paper presents results of a mechanically admissible drying process on the example of a prismatic bar dried convectively using the theory for drying of capillary-porous materials. The procedure of designing the safe drying processes, in which the destruction of dried materials no longer proceeds, is presented.
