... specifications. Finally, a discrete damage tolerance model embedded with 1.2 million kilometers periodic maintenance nodes is established and coupled with continuous crack propagation to realize quantitative full life fatigue assessment from initiation to maintenance limit. Findings The results show...

...Imad Barsoum; Hamda Almansoori; Aaesha Ahmed Almazrouei; Ebru Gunister Purpose The main aim of this study is to determine the fracture toughness and accordingly to predict the fracture initiation, crack propagation and mode of crack extension accurately in polypropylene subsea pipes subjected...

... origin of crack opening, estimation based on the readings from oscillograms shows uncharacteristically high velocities of the crack propagation. Design/methodology/approach Microscopic images of damaged absorbers showing the final result of the damaging process provided initial information about its...

... stress. A simplified approach for crack propagation analyses based on this finding showed limitations for application on larger cracks because it disregarded the increasing out-of-plane deformation for larger cracks as well as stress redistributions. The purpose of this paper is to improve the results...

...Spiros Pantelakis; Peter Horst; Julia Bierbaum; Peter Horst Purpose The purpose of this paper is to present the first results of tests where cracks lie in the tension field of a shear forced aluminium panel. The paper's main focus is on the crack propagation behavior and possible 3D‐effects caused...
