A Crack Propagation Method for Pipelines with Interacting Corrosion and Crack Defects [PDF]
Sensors, 2022 Corrosion and crack defects often exist at the same time in pipelines. The interaction impact between these defects could potentially affect the growth of the fatigue crack.

Velocity Fluctuations in Dynamical Fracture: the Role of Microcracks [PDF]
Physical Review E, 2004 We address the velocity fluctuations of fastly moving cracks in stressed materials. One possible mechanism for such fluctuations is the interaction of the main crack with micro cracks (irrespective whether these are existing material defects or they form

Dynamic interaction of cracks in piezoelectric and anisotropic solids: A non-hypersingular BIEM approach [PDF]
Theoretical and Applied Mechanics, 2008 A non-hypersingular traction boundary integral equation method (BIEM) is proposed for the treatment of crack systems in piezoelectric or anisotropic plane domains loaded by time-harmonic waves. The solution is based on the frequency dependent fundamental

Interaction of a finite crack with shear waves in an infinite magnetoelastic medium
Applied and Computational Mechanics, 2021 The aim of this paper is to investigate the interaction of a finite crack with shear waves in an infinite magnetoelastic medium. Fourier integral transformation is applied to convert the boundary value problem for a homogeneous,isotropic elastic material

Multi-Crack Dynamic Interaction Effect on Oil and Gas Pipeline Weld Joints Based on VCCT
Energies, 2022 In pipelines for transporting oil and gas, multiple cracks often exist in weld joints. The interaction among the cracks should be considered as it directly affects the life span of the pipeline structures. In the current investigation, based on the fluid–
