Deformation Behavior of Three-Dimensional Carbon Structures Under Hydrostatic Compression

The paper presents the results of numerical simulation aimed at studying the deformation behavior of carbon structures containing carbon atoms with various coordination numbers and, consequently, various electronic configurations and properties. Namely, the method of molecular dynamics was used to study the deformation behavior of two different structures of crumpled graphene (sp²-material formed by graphene flakes bonded by Van der Waals forces) and carbon diamond-like phases (rigid sp³-structures) under hydrostatic compression. Stress-strain curves have been obtained, structural features have been shown to affect mechanical properties of three-dimensional carbon structures.
