  1. 1. Fracture analysis of tensile- and fatigue failure for perforated and wedge wire structures

    M1-uppsats,

    Författare :David Barjosef; Alexander Austen Öhrn; [2022]
    Nyckelord :;

    Sammanfattning : In the effort to produce more durable filters and understand their mechanical failure, this study presents distinctive indicators on the cause of failure for welded perforated- and wedge wire sheets in 316L stainless steel, super duplex UR52N stainless steel and grade 2 titanium. The study achieves this by fracture analysis on specimens from tensile strength- and fatigue testing. LÄS MER
