“…It is this combination of an analytical approach and the use of computer capabilities that creates a single trajectory of constructing a solution to the contact problem for the die-elastic half-space system. This allows a holistic approach to the solution of complex practical problems based on a combination of numerical methods and existing software tools with analytical solutions, the experience of which can be found, for example, in works [20,23,24]. The advantages of this study in comparison with known ones are the combination of mathematical modeling and computer simulation for solving contact problems of the theory of elasticity.…”

“…In the same way, using a similar approach and already performed calculations, it is possible to search, for example, for areas of adhesion and sliding under a punch on the surface of an elastic half-space [23,24], using already developed software and the functionality of the CLIPS software system. Also, these results can be implemented in engineering strength calculations to increase the reliability and durability of structures or contribute to the saving of materials.…”

“…In a general form, the problem of determining the contour of the cross section of the punch interacting with the elastic half-space is stated [20,23,24]. With the help of the free software system CLIPS, (C Language Integrated Production System) (USA) [25], an expert system is built to automate the search for the most suitable punch form.…”

“…Since quite often in the case of solving practical problems, the geometric characteristics of stamps are not available for direct study, the evaluation of these parameters can be carried out in various ways [19,20,[23][24][25][26][27][28]. In this study, a knowledge base was built, which included information on the geometric characteristics and properties of the materials of stamps and half-space, information on the stressedstrained state of the punch-elastic half-space system.…”

The subject of this study is a punch-elastic half-space system under compressive force. The paper solves the problem of determining contact stresses and displacements. The content of results is the constructed models and the assessment of their adequacy. This work considers the problem of pressing a rigid plane double-connected punch on a homogeneous and isotropic elastic half-space. To obtain an analytical solution, a variant of the perturbation method based on the expansion of the potential of a simple layer distributed over a double-connected region by a small parameter was applied. The problem of pressing a flat punch in the form of a non-circular ring is reduced to a sequence of problems for a punch in the form of a circular ring. This allows us to use a known solution for a circular ring. Finite element models were built using ANSYS. A group of models was constructed to take into account possible damage in the event that the punch-elastic half-space system is exposed to difficult natural conditions or an aggressive environment during a certain time of modeling. A database was formed for the purpose of further transferring it to CLIPS. Sets of rules and knowledge were compiled. A generalizing algorithm was developed for the problems of constructing and analyzing mathematical and computer models of contact interaction between a rigid cylindrical punch with a flat double-connected base with an elastic half-space under the action of a compressive force. The problem of determining the geometric shape of the cross-section of an annular punch in the plan for the punch-elastic half-space system was solved for the case when the contact zone is not known in advance. The devised approach could be employed in engineering calculations for strength and durability
