Rast zamorne prsline u T zavarenom spoju legure aluminijuma.

Abstract

U ovom radu su prikazani inicijacija i rast prsline u T spoju ploče od aluminijumske legure AA2024 –T351, zavarenom mešanjem trenjem (Friction Stir Welding - FSW), primenom mehanike loma. Svi analizirani modeli su napravljeni od legure 2024-A351. Osobine materijala i dimenzije u oblasti FSW spoja su usvojene na osnovu dostupnih eksperimenata...

In this present work, application of fracture mechanics is used to present a fatigue crack initiation and growth of friction stir welded (FSW) T joint plate made of aluminum alloy AA2024 –T351. All analyzed models are made from aluminum alloy 2024-T351.The properties of materials in the areas of joints and geometry measures of FSW joint are adopted from available experiments...
