Konstitutivnaya Uprugovyazkoplasticheskaya Model' Gtsk-polikristallov: Teoriya, Algoritmy, Prilozheniya A.i. Shveykin Russian edition

Matematicheskoe modelirovanie protsessov neuprugogo deformirovaniya metallov (yavlyayushchikhsya, kak pravilo, polikristallicheskimi) v razlichnykh tekhnologicheskikh protsessakh predstavlyaet soboy ves'ma slozhnuyu zadachu, t.k. mekhanicheskie kharakteristiki polikristallicheskikh materialov opredelyayutsya razmerami, strukturoy, fizicheskimi svoystvami i vzaimodeystviem kristallicheskikh zeren, prichem protsessy intensivnogo plasticheskogo deformirovaniya polikristallicheskikh tel vsegda soprovozhdayutsya sushchestvennoy evolyutsiey mikro- i mezostruktury materiala, chto opredelyaet deformatsionnoe povedenie materiala na makrourovne. V knige predlagaetsya matematicheskaya model' neuprugogo deformirovaniya polikristallicheskogo agregata, kachestvenno i kolichestvenno opisyvayushchaya evolyutsiyu mikrostruktury i fiziko-mekhanicheskikh kharakteristik pri izotermicheskom deformirovanii odnofaznykh polikristallicheskikh GTsK?metallov na razlichnykh strukturnykh urovnyakh. Predlagayutsya podkhody k opisaniyu razvorotov kristallicheskikh reshetok zeren, fragmentatsii, uprochneniya. Privodyatsya rezul'taty modelirovaniya nekotorykh tekhnologicheskikh protsessov: osadki, stesnennoy osadki, ravnokanal'nogo uglovogo pressovaniya (v t.ch. evolyutsii funktsii raspredeleniya orientatsiy zeren).
