Autor: Anna A. Okunkova, Jury Bublikov, Nataliya Kapustina, Aleksei Osinnii, Anatoli Chigarev

Publikováno v: EPJ Web of Conferences, Vol 248, p 04009 (2021)

The article proposes a model of the ultimate stress state of the material of the coated tool cutter. It is found that with an increase in the fracture toughness of a tool in connection with the material ductility the machining accuracy deteriorates d

Mathematical Modeling of Shock Waves in Inhomogeneous Viscoelastic Two-Component Media

Autor: Victor Polenov, Anatoli Chigarev

Publikováno v: Journal of Applied Mathematics and Physics. :997-1005

Mathematical modeling of two-component media with a saturated liquid began over 90 years with studies of the consolidation of soils. Two-component must be taken into account when solving a significant number of applied problems arising in various are

Simulation of Tsunami Effect by Seismic Wave Propagation in Hypoplastic Medium at Vicinity of Free Boundary

Autor: Anatoli Chigarev, Victor Polenov, Pavel Shirvel

Publikováno v: Universal Journal of Mechanical Engineering. 6:9-20

A theoretical study of seismic waves propagation in a soil layer with a free surface has a great importance for a prediction in engineering decisions. Wave packets are radiated from an earthquake source and transfer energy. A transformation and a sel

Reliability Calculation for a Multilayered Coating Based on a Model with Independently (Sequentially) Degrading Layers

Autor: Aleksei Osinnii, Anatoli Chigarev, Jury Bublikov, Mikhail Mosyanov, Anton Kekalo

Publikováno v: EPJ Web of Conferences, Vol 248, p 04010 (2021)

The paper proposes methods to predict the reliability of a multilayered coating based on a model with independently (sequentially) degrading layers. For the mathematical description of the process of crack penetration into the depth of a layered soli

Variational determination of the crack trajectory in inhomogeneous media

Autor: Miklashevich, I. A., Anatoli Chigarev, Korsunsky, A. M.

Publikováno v: Scopus-Elsevier
ResearcherID

Propagation of a crack through inhomogeneous media is considered in the variational formulation, whereby the path corresponding to the extremum of energy release during fracture is sought. A non-linear differential equation is obtained for the crack
