Experimental Investigation of Fatigue Crack Growth Behavior in Banded Structure of Pipeline Steel
Metals, 2020 The effect of a ferrite/mixed phase banded structure on the fatigue crack growth behavior of pipeline steel has been investigated in this work. Constant stress-controlled fatigue tests were carried out on unilateral notch specimens in the longitudinal ...

Metals, 2021 Fatigue of materials, like alloys, is basically fatigue-crack growth in small cracks nucleating and growing from micro-structural features, such as inclusions and voids, or at micro-machining marks, and large cracks growing to failure.

Predicting crack growth in viscoelastic bitumen under a rotational shear fatigue load
International Journal on Road Materials and Pavement Design, 2019 This study develops a damage mechanics-based crack growth model to predict crack length in a typical viscoelastic material (i.e. bitumen) under a rotational shear fatigue load. This crack growth model was derived using torque and dissipated strain energy

Two-Parameter Mechanistic model for the Fatigue Crack Growth of Metals
NUST Journal of Engineering Sciences, 2019 In this paper, a two-parameter mechanistic model for the fatigue crack growth has been developed. Fatigue failure is the major causes of mechanical structural failure. The fatigue failure progress in three stages crack initiation, crack growth and final
