Micromechanical fracture models can be used to predict ductile fracture initiation for welded
steel connections under strong earthquake. The parameter influencing factors of four such …

This paper calibrates micromechanical fracture models for duplex stainless steel in order to
study its fracture behaviour under seismic loading, characterized by large strain ultra low …

Uniaxial tensile tests were conducted on smooth round bar specimens made of Q460D high-
strength steel base metal and ER55-G welds after a high temperature of 900° C and natural …

In order to predict the ductile fracture of beam-column connections with initial defects, the
finite element models of the existing Q460C high-strength steel local connection specimens …

To investigate the fracture properties of weathering steel Q355GNHB, calibrate its
mesoscopic fracture model parameters, and realize the prediction of the fracture behavior of …

When high-strength steel is heated to high temperatures and then cooled naturally, its
ductility decreases. In earthquake-prone areas, it is necessary to evaluate the ultra-low cycle …

To promote the applicability and the instantaneity of the steel fracture model, by adopting the
concept of the ductile damage factor, the VGM-DDF and JC-DDF fracture predicted models …

The Stress-weighted Damage Model (SWDM) based on microscopic fracture mechanism
can be used to predict the ductile fracture of steel by considering the influence of lode angle …
