| Abstract: | 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. |
