In the literature, there are algorithms associated with the design of simulations of technological processes, in which the material model has always been defined previously. However, in none of the studies of computer simulation modelling of technological processes known to the authors of this article, is there a detailed description of how the algorithm, or the selection of plastic model used, is subject to this process. This article is an attempt to develop a general algorithm for the very difficult stage in the design of computer simulations of technological processes, which is the choice of the appropriate subject material for the constitutive model of the technological process. In other words, the article addresses only the issue of constitutive strain-stress relations. In the literature, there is a lack of algorithms for the systematic mathematical selection of model materials for the design phase of computer simulations with regard to mechanical bodies. This paper is an attempt to develop, without program implementation, such a specific algorithm for the model material selection in the design phase of computer simulation. Development of an algorithm for the selection of suitable model material model under computer simulation provides opportunities and most importantly, it reduces the required level of education of the people creating the simulation of the technological processes; thus, the group of consumers for whom the numerical computations may be relevant, is increased.
