A possible method of computer-aided design of materials with a highly porous matrix structure based on the method of moving cellular automata

Three-dimensional movable cellular automata simulation of elastoplastic deformation and fracture of coatings in contact interaction with a rigid indenter

“…The next step for identification of nanodefects in the coating material is to determine the frequencies characterizing the size of defects and their period [28]. We studied how the location depth of nanopores, their shape, and the specimen thickness influence the identification of frequencies due their presence.…”

“…1a) and relative tangential displacement shear ij l (.ig. 1b) calculated with regard to rotation of both automata [28,29]. Note that although the last expression in Eq.…”

The effect of elastic energy accumulation and the possibility of controlling the fracture process in complex structures

“…In this work, we have simulated the loading of flat samples with a shape resembling construction of the front part of a car frame. The mechanical characteristics of a material studied corresponded to those of a ZrO 2 ceramics, for which the parameters of mobile cell automats are well determined [4,8]. The sample, composed of the 0.1-cm automats, had a total width of 4 cm and a height of 5 cm.…”

“…Problems of these kinds can be solved based on the method of mobile cell automats extensively developed in recent years. This method was successfully used in simulations of the fracture of various materials and constructions [4][5][6][7][8].…”

“…In optimizing the structure of a material intended for use under the dynamic loading conditions, it is necessary to take into account a possibility that redistribution of the elastic energy (related, e.g., to phase transitions, generation and accumulation of microscopic damage, etc.) would change the mechanical properties of the material in the course of loading [1][2][3][4].…”
