20.500.12556/DKUM-92216 Yield load solutions for SE(B) fracture toughness specimen with I-shaped heterogeneous weld The objective of this work was to investigate the fracture behavior of a heterogeneous I-shaped welded joint in the context of yield load solutions. The weld was divided into two equal parts, using the metal with the higher yield strength and the metal with the lower yield strength compared to base metal. For both configurations of the I-shaped weld, one with a crack in strength in the over-matched part of the weld and one for a crack in the under-matched part of the weld, a systematic study of fracture toughness SE(B) specimen was carried out in which the crack length, the width of the weld and the strength mismatch factor for both weld metals were varied, and the yield loads were determined. As a result of the study, two mathematical models for determination of yield loads are proposed. Both models were experimentally tested with one strength mismatch configuration, and the results showed good agreement and sufficiently conservative results compared to the experimental results. yield load heterogeneous weld numerical analysis SE(B) specimen donosna obremenitev heterogeni zvarni spoji numerična analiza SE(B) primerek true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/materials © 2021 by the authors.
