The Relationship of Fatigue and CTOD about E43 Steel

DEStech Transactions on Computer Science and Engineering, 2018
Because of the inevitable defects inherently exist in the bridge steel structure, the steel E43 specimen was under fatigue and CTOD (Crack tip opening displacement) test. The results provide an experimental base and computing foundations for the bridge steel-using. This paper studies the CTOD fatigue precracking experiment on steel E43.

A numerical analysis of fatigue crack closure using CTOD

Procedia Structural Integrity, 2019
The crack closure level was determined numerically using the finite element method for six materials and different load conditions. The crack opening level was found to be higher than the crack closure level and a value of 0.9 was obtained for the ratio ...
