Annotatsiya

Dolzarbligi. Ishda bir jinsli kvadrat kesimli sterjenning ketma-ket va proporsional yuklash usullarida elastik-plastik cho‘zilishi va buralishi tadqiq qilingan. Usullar. Hisoblash deplanatsiya funksiyasini aniqlashga asoslangan. Prandtl–Reuss modeli bo‘yicha olingan yechim deformatsiyalanish trayektoriyasi xotirasini hisobga oluvchi o‘rtacha egrilik nazariyasi bo‘yicha hisob-kitoblar bilan taqqoslangan. Masalani yechish uchun besh nuqtali ayirmalar sxemasiga ega chekli ayirmalar usuli qo‘llanilgan. Natijalar. Uchta to‘rda test elastik masalasi uchun yaqinlashishning ikkinchi tartibi tasdiqlangan. Taqdim etilgan taqqoslashda bir xil yakuniy kinematik holatda o‘rtacha egrilik nazariyasi bo‘yicha olingan moment qiymati Prandtl–Reuss modeli bo‘yicha olingan natijadan 9,44% gacha yuqori bo‘lgan. Xulosa. Mahalliy trayektoriyalar plastik deformatsiyaning yuklanish turiga sezgirligini ko‘rsatadi.
