INFLUENCE OF LARGE DEFORMATION CYCLIC LOADING HISTORY ON DUCTILE CRACK GROWTH OF STEEL MEMBERS

The purpose of this study is to clarify the influence of loading history on ductile crack growth in order to study the influence of loading history on the deformation capacity of steel members under large cyclic deformation. Cyclic loading tests are conducted to confirm the influence of the change of loading amplitude on the change of tensile load occurred from ductile crack growth. Then, FEM analysis which reproduces ductile crack growth is conducted in order to confirm the plastic strain distribution ahead of ductile crack. From these, the influence of loading history on ductile crack growth is clarified.
